Abstract For the amount of aspirin in a commercial tablet to be determined‚ different solutions of acetylsalicylic acid mixed with NaOH were created at different concentrations. All the different solutions were then analysed using Novaspec photometer‚ which allowed for a graph to be created and a line of best fit to be made. The amount of aspirin in a commercial tablet was found to be 350mg. Introduction The molecular formula for aspirin‚ also known as acetylsalicylic acid‚ is C9H8O4. It is most

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

Formal Report no. 1 Synthesis of Aspirin Chemical Principles Aspirin is most widely sold over-the-counter drug. It has the ability to reduce fever (an antipyretic)‚ to reduce pain (an analgesic)‚ and to reduce swelling‚ soreness‚ and redness (an anti-inflammatory agent). Much of this is believed to be due to decreased production of prostaglandins and thromboxanes. Aspirin’s ability to suppress the production of prostaglandins and thromboxanes is due to its irreversible inactivation of the cyclooxygenase (COX)

Formal Lab Report 1 Chemistry 100-03 March 19‚ 2012 Abstract: • Introduction/Objective: Prepare and analyze aspirin from salicylic acid and acetic anhydride‚ and calculate the percent yield of the synthesized aspirin. • Materials and Methods: This experiment called for the synthesis of acetylsalicylic acid‚ or aspirin‚ by using salicylic acid‚ acetic anhydride‚ sulfuric acid‚ and vacuum filtration. The salicylic acid and the acetic anhydride were mixed in a flask. Sulfuric

Lab Report Introduction This lab has the following two concepts: synthesis of acetylsalicylic acid and analysis of acetylsalicylic acid. Synthesis is a purposeful execution of chemical reactions to obtain a product. This concept is used in the first part of the lab; when we have to produce crystals of aspirin. Analysis is the separation‚ identification‚ and quantification of the chemical components of natural and artificial materials. This concept is used throughout the lab when we are analyzing

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

Case Study #1 Metallgesellschaft AG Metallgesellschaft Refining and Marketing (MGRM)‚ was a subsidiary of Metallgesellschaft AG in Germany. In the early 90’s‚ MGRM chose to being selling long term (5 and 10 year) fixed price contracts for gasoline‚ heating oil‚ and diesel fuel. These contracts were successfully marketed with MGRM contracted for 160 million barrels of oil as of Nov 1993. Due to the fact that the MGRM entered into long term commitments for fuel delivery with fixed pricing‚ this
