Introduction: The purpose of this lab was to learn how to use salicylic acid to make aspirin. Aspirin is the most widely used over-the-counter drug in the world. The average tablet contains about 325 milligrams of acetylsalicylic acid with an inert binding material such as starch. Aspirin is used to relieve pain‚ reduce inflammation‚ and lower fever. Aspirin originally was derived by boiling the bark of the white willow tree. Although the salicin in willow bark has analgesic properties‚ purified

INTRODUCTION: Penicillin is the basis for most of the antibiotics in the world just as aspirin is the basis for many drugs. Therefore‚ if there had been only two drugs to invent‚ it would be down to penicillin and aspirin. Hippocrates‚ the father of modern medicine lived sometime between 460 B.C and 377 B.C. Hippocrates has left historical records of pain relief treatments‚ including the use of a powder made from the bark and leaves of the willow tree to help heal headaches‚ pains and fevers.

synthesize and purify aspirin. The theoretical yield was calculated to 3.766g. The actual yield of pure aspirin was 2.863g with a yield of 76%. The percent yield indicates that our synthesis was a success but the yield is low and indicates that some of the aspirin was lost during synthesis. Some reasons for loss can result from human error such as loosing product from sticking on the spatula and the Buchner funnel and several weighings. Also‚ when transferring the crude aspirin into the vacuum filtration

effects for some people‚ yet it is safe enough to be sold without a prescription. Because it is easy to prepare‚ aspirin is one of the most inexpensive drugs available. It is produced in vast amounts. In fact‚ industry makes 43‚000‚000 pounds of the drug every year. This microscale experiment will permit you to make an amount of aspirin equivalent to about 1/2 of that found in an aspirin tablet. Purpose: To synthesize acetylsalicylic acid on a microscale basis.

Synthesis of Aspirin Chemistry Standard Level Lab Report Data Collection and Processing and Conclusion and Evaluation Date: December 8th‚ 2011 Purpose: The purpose of this lab was to synthesize aspirin‚ determine the theoretical yield‚ compare the percent yield to the theoretical yield and test the purity of aspirin by adding Iron (III) chloride to the product. Hypothesis: I hypothesize that salicylic acid will react with acetic anhydride to produce acetylsalicylic acid (aspirin) and

Sodium chloride‚ also known as salt‚ common salt‚ table salt‚ or halite‚ is an ionic compound with the formula NaCl. Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt‚ it is commonly used as a condiment and food preservative. [edit] Properties Thermal conductivity of pure NaCl as a function of temperature has a maximum of 2.03 W/(cm K) at 8 K and decreases to 0.069 at 314

Lab 1: Synthesis of Aspirin Introduction: The purpose of this lab was to demonstrate the ability to easily alter the molecular structure of a compound to greatly increase its utility. In this case‚ an acetyl group was added to salicylic acid‚ a naturally occurring compound with significant pharmaceutical value. Without the addition of the acetyl group‚ salicylic acid is an irritant to the gastro-intestinal (GI) tract. Once the acetyl group is added via a simple reaction‚ acetylsalicylic
