Synthesis of Aspirin Lab Report - 2989 Words

Abstract: The goal of this experiment was to synthesize aspirin. In this experiment aspirin, also known as acetylsalicylic acid, was synthesized from salicylic acid and acetic anhydride. In the reaction the hydroxyl group on the benzene ring in salicylic acid reacted with acetic anhydride to form an ester functional group. This method of forming acetylsalicylic acid is an esterification reaction. Since this esterification reaction is not spontaneous, sulfuric acid was used as a catalyst to initiate the reaction. After the reaction was complete some unreacted acetic anhydride and salicylic acid was still be present in the solution as well as some sulfuric acid, aspirin, and acetic acid.

Aspirin became commercially available in 1899 and today it is estimated that over a trillion aspirin tablets have been consumed by those in need of its cur ative effects. In this experiment aspirin was synthesized from salicylic acid and acetic anhydride. Salicylic acid was esterfied using acetic acid and sulfuric acid acting as a catalyst to produce acetylsalicylic acid and acetic acid. The phenol group that will attack the carbonyl carbon of the acetic anhydride is the –OH group that is directly attached to the benzene since it is more basic than the –OH group attached to the carbonyl group. This method of forming acetylsalicylic acid is an esterification reaction. Since this esterification reaction is not spontaneous, sulfuric acid was used as a catalyst to initiate the reaction. Sulfuric acid serves as the acid catalyst since its conjugate base is a strong deprotonating group that is necessary in order for this reaction to be reversible. The need for the strong conjugate base is the reason why other strong acids such as HCl is not used since its conjugate base Cl- is very weak compared to HSO3-. After the reaction was complete some unreacted acetic anhydride and salicylic acid was still be present inShow MoreRelatedS ynthesis Of Aspirin Lab Report1101 Words   |  5 PagesExperiment 19: Synthesis of Aspirin and Oil of Wintergreen The purpose of this experiment was to employ techniques to synthesize aspirin and oil of wintergreen and to purify crude aspirin via recrystallization.

Why Do You Believe Inhibit Your Learning Process - 932 Words

1. Consider all the thinking traps people tend to use. Which ones do you encounter most in your own thinking? Which do you believe inhibit your learning process? One thinking trap I deal with, and try to be mindful of, is that I tend to be too quick in deciding. I look at the facts that are available and make a quick decision in order to move on to the next task. A trap that inhibits my learning process is being a victim of personal habits and prejudices. I have my mind set very firm of a lot of things, this affects me when trying to learn new things (as well as try new things). 2. Compare and contrast command, consultative and consensual decisions. Which do you prefer? A command decision is when managers make on their own, with little or no input from others. In a consultative decision managers use input and opinions from others but make the final decision. Lastly, a consensus decision is made democratically by a group, it is a joint decision. I prefer the conceptive decision making process. The front line has very valuable insight into the day to day activities and that is key when making a reasonable decision. At the same time, the front line usually lacks the bigger picture and the full disclosure of the situation. 3. Do you support the findings of whole brain research? If not, what problems do you see?

Reflexology Essay Example For Students

Reflexology Essay The origins of Reflexology evidently reach back to ancient Egypt as evidenced by inscriptions found in the physicians tomb at Saqqara in Egypt. The translation of the hieroglyphics are as follows: Dont hurt me. The practitioners reply:- I shall act so you praise me. We cannot determine the exact relationship between the ancient art as practiced by the early Egyptians and Reflexology as we know it today. Different forms of working the feet to effect health have been used all over the ancient world. Dr. Riley maintained that this form of healing spread from Egypt via the Roman Empire. The Zone Theory was the precursor to modern Reflexology which began with Dr. William H. Fitzgerald, M.D. whom Dr. Edwin Bowers, M.D., encouraged to publish the many articles he had written on the subject of Zone Analgesia. In the forward to their combined book, Relieving Pain At Home published in, 1917, he wrote, Humanity is awakening to the fact that sickness, in a large percentage of cases, is an error of body and mind. How true this has proved to be. Dr. Fitzgerald, was an Ear, Nose and Throat specialist working at the Boston City Hospital, as well as at St Francis Hospital in Connecticut. He called his work Zone Analgesia where pressure was applied to the corresponding bony eminence or to the zones corresponding to the location of the injury. He also used pressure points on the tongue, palate and the back of the pharynx wall in order to achieve the desired result of pain relief or analgesia. He made use of the following tools: elastic bands, clothes pegs and aluminum combs, on the hands, surgical clamps for the tongue, nasal probes and a regular palpebral retractor for the pharynx, He was responsible for formulating the first chart on the longitudinal zones of the body. Dr. Fitzgerald discovered a very interesting fact, that the application of pressure on the zones not only relieved pain but in the majority of cases also relieved the underlying cause as well. The same result is experienced through Reflexology today, which is based partially on the Zone Theory. Dr. Shelby Riley, M.D. worked closely with Dr. Fitzgerald and developed the Zone Theory further. It seems that he added horizontal zones across the hands and feet, together with the longitudinal zones and thus determining individual reflexes according to the Zone Theory. He, like Fitzgerald, espoused continual pressure on the reflex or point of contact. Eunice D. Ingham, a Physical Therapist, worked closely with Dr. Riley and was fascinated by the concept of Zone Therapy and started developing her foot reflex theory in the early 1930s. She had the opportunity to treat hundreds of patients where each reflex point of contact had been carefully and thoughtfully checked and rechecked until with all confidence she was able to determine that the reflexes on the feet were an exact mirror image of the organs of the body. Dr. Riley encouraged her to write her first book entitled Stories The Feet Can Tell where she documented her cases and carefully mapped out the reflexes on the feet as we know them today. This book was published in 1938 and was later translated into seven foreign languages which spread the benefits of Reflexology way beyond the borders of the States. The confusion between Reflexology and Zone Therapy started at this point because the foreign publisher changed the name of Eunices book, The Stories The Feet Can Tell to Zone T herapy and in some parts of the world it is still thought of as Zone Therapy. However, there is a distinct difference between the two therapies. Zone Therapy relies solely on the zones to determine the area to be worked, whereas Reflexology takes the zones as well as the anatomical model to determine the area or areas to be worked. After the publication of her book Eunice Ingham found herself on the program at many health seminars. She traveled around the country giving book reviews. Only sick and dilapidated people attended these book reviews/ seminars where she would teach people by working on them and discuss their particular health problems. As these sick people, whom everyone else had given up on, got better the word

All About the Great Lakes of North America

All About the Great Lakes of North America Lake Superior, Lake Michigan, Lake Huron, Lake Erie, and Lake Ontario, form the Great Lakes, straddling the United States and Canada to make up the largest group of freshwater lakes in the world. Collectively they contain 5,439 cubic miles of water (22,670 cubic km), or about 20% of all the earth’s fresh water, and cover an area of 94,250 square miles (244,106 square km). Several other minor lakes and rivers are also included in the Great Lakes region including the Niagra River, Detroit River, St. Lawrence River, St. Marys River, and the Georgian Bay. There are 35,000 islands estimated to be located on the Great Lakes, created by millenia of glacial activity. Interestingly, Lake Michigan and Lake Huron are connected by the Straits of Mackinac, and can be technically considered a single lake. The Formation of the Great Lakes The Great Lakes Basin (the Great Lakes and the surrounding area) began to form about two billion years ago – almost two-thirds the age of the earth. During this period, major volcanic activity and geologic stresses formed the mountain systems of North America, and after significant erosion, several depressions in the ground were carved. Some two billion years later the surrounding seas continuously flooded the area, further eroding the landscape and leaving a lot of water behind as they went away. More recently, about two million years ago, it was glaciers that advanced over and back across the land. The glaciers were upwards of 6,500 feet thick and further depressed the Great Lakes Basin. When the glaciers finally retreated and melted approximately 15,000 years ago, massive quantities of water were left behind. It is these glacier waters that form the Great Lakes today. Many glacial features are still visible on the Great Lakes Basin today in the form of glacial drift, groups of sand, silt, clay and other unorganized debris deposited by a glacier. Moraines, till plains, drumlins, and eskers are some of the most common features that remain. The Industrial Great Lakes The shorelines of the Great Lakes stretch a little over 10,000 miles (16,000 km), touching eight states in the U.S. and Ontario in Canada, and make an excellent site for the transportation of goods. It was the primary route used by early explorers of North America  and was a major reason for the great industrial growth of the Midwest throughout the 19th and 20th century. Today, 200 million tons a year are transported using this waterway. Major cargoes include iron ore (and other mine products), iron and steel, agriculture, and manufactured goods. The Great Lakes Basin also is home to 25%, and 7% of Canadian and U.S. agricultural production, respectively. Cargo ships are aided by the system of canals and locks built on and between the lakes and rivers of the Great Lakes Basin. The two major sets of locks and canals are: 1) The Great Lakes Seaway, consisting of the Welland Canal and the Soo Locks, allowing ships to pass by the Niagra Falls and the rapids of the St. Marys River. 2) The St. Lawrence Seaway, extending from Montreal to Lake Erie, connecting the Great Lakes to the Atlantic Ocean. Altogether this transportation network makes it possible for ships to travel a total distance of 2,340 miles (2765 km), all the way from Duluth, Minnesota to the Gulf of St. Lawrence. In order to avoid collisions when traveling on the rivers connecting the Great Lakes, ships travel upbound (west) and downbound (east) in shipping lanes. There are around 65 ports located on Great Lakes-St. Lawrence Seaway system. 15 are international and include: Burns Harbor at Portage, Detroit, Duluth-Superior, Hamilton, Lorain, Milwaukee, Montreal, Ogdensburg, Oswego, Quebec, Sept-Iles, Thunder Bay, Toledo, Toronto, Valleyfield, and Port Windsor. Great Lakes Recreation About 70 million people visit these the Great Lakes every year to enjoy their water and beaches. Sandstone cliffs, high dunes, extensive trails, campgrounds, and diverse wildlife are just some of the many attractions of the Great Lakes. It is estimated that $15 billion is spent every year on leisure activities every year. Sport fishing is a very common activity, partly because of the Great Lakes size, and also because the lakes are stocked year after year. Some of the fish include bass, bluegill, crappie, perch, pike, trout, and walleye. Some non-native species such as salmon and hybrid breeds have been introduced but have generally not succeeded. Chartered fishing tours are a major part of the Great Lakes tourism industry. Spas and clinics are popular tourist attractions also, and couple well with some of the serene waters of the Great Lakes. Pleasure-boating is another common activity and is more successful than ever as more and more canals are built to connect the lakes and surrounding rivers. Great Lakes Pollution and Invasive Species Unfortunately, there have been concerns about the quality of water of the Great Lakes. Industrial waste and sewage were the primary culprits, specifically phosphorus, fertilizer, and toxic chemicals. In order to control this issue, the governments of Canada and the United States joined to sign the Great Lakes Water Quality Agreement in 1972. Such measures have drastically improved the quality of water, though pollution still finds its way into the waters, primarily through agricultural runoff. Another major concern in the Great Lakes is non-native invasive species. An unanticipated introduction of such species can drastically alter evolved food chains and destroy local ecosystems. The end result of this is a loss of  biodiversity. Well known invasive species include the zebra mussel, Pacific salmon, carp, lamprey, and alewife.

Cro- Magnons

entrances, while others built huts in forested areas. As better hunting methods developed, Cro-Magnons built more permanent homes. Long houses holding many families were made of stone blocks. There is archaeological evidence that communities of 30 to 100 people lived together. To their technological advances, the Cro- Magnons added accomplished artistry. They creat- ed cave paintings like those found at Lascaux (la .sKOH) and Vallon-Pont-d' Arc (vah. YOHN pohn DAHRK), both in France, as well as those at numerous other cave sites in Spain and Africa. Researchers so far can only speculate on the pur- pose behind the mysterious wall images. Perhaps the hunting scenes were educational, designed to teach young hunters how to recognize prey. On the other hand, the Cro-Magnon painters may have been reaching out to the spiritual world, creating images meant to have mystical powers that would help the hunters. Archaeologists have discovered some Cro- Magnon figures sculpted from clay or carved from reindeer antlers. They have also found figures of ivory and bone decorated with animal drawings and abstract designs. Some of these artifacts may well have been used in magic rituals and probably reflect Cro-Magnon beliefs about spirits thought to live in animals, plants, the earth, and the sky. During the Neolithic period and immediately after, humanity made one of its greatest cultural advances. New environments had developed with the end of the last Ice Age, and forests and grass- lands appeared in many areas. Over some 5,000 years, people gradually shifted from gathering and hunting food to producing food. Because new agri- cultural methods led to tremendous changes in peoples' lifestyles, this period is usually called the Neolithic Revolution.

European Sovereign-debt Crisis Research Paper Example | Topics and Well Written Essays - 1500 words

European Sovereign-debt Crisis - Research Paper Example Attempts by international monetary fund (IMF) to avail 750 billion Euros to financially support countries with high debt situation did not mitigate the situation. The paper will, therefore, explore on the causes and evolution of the debt crisis, its impact on the US market, and some interventions undertaken by the US to mitigate the impact. Causes of the Crisis Many factors can be attributed to the crisis that has seen the credit ratings of countries decline and caused shock in the global financial markets. The European Union has been accused of failing to take timely actions and of lingering until the situation ran out of hand. The crisis resulted from a mixture of several complex factors like the globalization of finance, international imbalances in trade, housing bubbles, ease credit conditions between 2002 and 2008 that resulted into high risk lending, and the slow economic growth in the year 2008 (Frangakis, 2006). The factors are elaborated below. a) Increased debt level EU mem bers signed a Maastricht treaty in 1992 where members promised to limit their deficit spending and debt amounts. However, the member countries like Greece and Italy failed to adhere to the agreements of the treaty and instead used complex currency and credit derivatives to increase their debt levels. From the data, the debt levels rose because of the large bailout given to financial sector in the late 2000s and the 2008 economic recession. In 2007, the percentage of fiscal deficit was 0.6 before it rose to 7% during the crisis (Frangakis, 2006). The government debt simultaneously rose to 84% from 66% of the GDP. The crisis can thus be attributed to the inappropriate fiscal policy choices and the actions by the governments to bail out troubled banks. The variations in how different countries used borrowed funds resulted in different effects. Ireland banks, for example, increased their lending to property developers, which later led to the housing bubble. Greece, on the other hand, in creased its pledge to the government workers of salary increment and pension rise. These actions increased the government level of debt, which later made it difficult for the states to meet their obligations as they became due. b) Trade imbalances The crisis grew because of the increasing trade imbalances. An increase in the amounts of trade deficits increases the levels of debt hence increasing the debt crisis. Before the commencement of the debt crisis, the trade deficit of Italy, France, and Greece increased, while that of Germany recorded trade surplus. However, Greece position has improved because of the decline in the imports and increment for exports. c) Loss of confidence Immediately after the crisis developed, it became clear that the bonds of weaker economies like Greece were risky. Because of this loss of confidence, sovereign CDS prices rose to match the market expectation of the increased debt. Investors also doubted the ability of the countries to contain the crisis be cause EU countries have few monetary policy choices. d) Monetary Policy Inflexibility Monetary policy inflexibility of all member states of EU established a common monetary policy and used one currency. Countries were, therefore, unable to print money in order to devalue their currency to stimulate exports and reduce the debt level through trade surpluses. Greece and other member states, therefore, lacked

Human Resource Development-Coaching and Performance Management Research Paper - 1

Human Resource Development-Coaching and Performance Management - Research Paper Example In workplaces coaching has began to move from being the latest management fad to a mainstream component of talent management and organization development. The growing popularity of coaching as a method of human and organizational change carries with it an enormous opportunity and challenge for those who deliver coaching training and services. One of the principle challenges of coaching is ‘professionalization’. Continued customer demands, increased consumer sophistication, and nature of work create pressure for coaching to move from being an industry to a profession. In the service sector, branding, competition, proprietary product and models are the order of the day. The three most important challenges that coaching faces in moving towards a professional footing are- Evidence based approach to coaching means producing evidence that any specific intervention is effective, or being able to demonstrate the return on investment. It also refers to the intelligent and conscientious use of the ‘best current knowledge’ for decision making and delivering coaching to clients and designing and teaching coach training programs. The best current knowledge from the above line refers to the updated information from relevant, valid research, practice and theory (Gravells, 2006, P.3) Behavioural science is the fundamental for the development of the evidence based coaching because the research skills of the practitioners are essential for evaluating the effectiveness of the coaching methodologies. According to an article by Stephen J Dorgan and John Dowdy governments around the world have been committed to raising the productivity for improving the economic performance. In a research by McKinsey Global Institute (MGI) it has been demonstrated yhat for the past three decades productivity at the sector level is driven by the degree to which these companies are exposed to competition. The main argument that has been
