CHEM%2315%Fall%2014% Creating useful and beautiful molecules using synthetic organic chemistry – Synthesis of Aspirin and Indigo INTRODUCTION Aspirin Salicylic acid occurs naturally in the bark of willow trees. Prior to the 1800’s‚ willow bark was often brewed into a tea‚ or chewed to relieve pain. While the salicylic acid is effective at reducing pain it was found to irritate the lining of the stomach. It was mostly by chance that on August 10‚ 1897 Felix Hoffmann‚ a German chemist who obtained

“Team Marketplace Assignment” “Tide vs. Store Brand” Laundry detergent is a very necessary item and can be found in many varieties at local grocery stores. However‚ some brands tend to overpower others. During our team marketplace assignment we compared two different detergents at two different locations. We compared Tide and the generic brand detergent at both Harris Teeter and Food Lion. We compared the differences and similarities of each brand. We also observed the positioning‚ prices‚ promotions

ANALYSIS OF ASPIRIN: SPECTROPHOTOMETRY The purpose of this experiment is to evaluate the percent aspirin on a commercial aspirin tablet using an instrumental method‚ spectrophotometry. In a spectrophotometer‚ light from a strong lamp passes through a monochromator‚ which breaks the light into its component colors using a grating‚ then uses mirrors and slits to direct a light beam of the desired wavelength through the sample compartment‚ where you place a tube (cuvette) of solution. A detector

Consumer Perceptions of Store Brands Presented By: Chris Frimel Jeffrey Fox L. Renee Graves Dustin Huffman Introduction Consumer perception heavily influences consumption and spending behavior. As consumers search for ways to stretch their tight budgets‚ many factors motivate these behaviors. Such factors include loyalty‚ convenience‚ quality‚ quantity‚ usages‚ product placement‚ and many others. Of these factors‚ price‚ quality‚ and convenience are most sought after when consumers

What is the more formal chemical name for aspirin? Acetylsalicylic acid 2. Using your data from Experiment 2‚ how can you be sure you synthesized aspirin? By using the colors as a guide‚ we can compare the Acetylsalicylic acid + 8 mL FeCl3 to the Aspirin Crystals from Experiment 1 + 8 mL FeCl3 in order to see if it synthesized. 3. Would you say that your synthesized aspirin is relatively pure? How can you tell? One way that the purity of aspirin can be judged is by it’s color as pure acetylsalicylic

diabetes but no other major risk factors for heart disease probably should not be on low-dose aspirin therapy‚ new research suggests. The new recommendations are based on close examination of nine studies that found the risks of some aspirin side effects‚ such as stomach bleeding‚ should be better balanced against the possible benefits of using aspirin. The larger theme here is that use of low-dose aspirin to prevent heart attacks in people who have not already experienced one is probably not as efficacious

Aspirin Synthesis Introduction Out of all the pharmaceutical drugs in the worlds‚ aspirin is made the most. Any potential pharmacist must be familiar with synthesizing the drug. The goal of this lab is to synthesize as much pure aspirin as possible. The reactants‚ acetyl anhydride and salicylic acid‚ must react in phosphoric acid. With phosphoric acid as a catalyst‚ the reaction yields aspirin and acetic acid. The equation for the reaction is as follows: “(CH3CO)2O + HOC6H4COOH □(→┴yields ) CH3CO2C6H4CO2H
