Synthesis of Aspirin Learning Goals 1. To synthesize aspirin from salicylic acid and acetic anhydride. 2. To purify the crude product by Recrystallization. Introduction Most drugs are chemical compounds which are described as "organic compounds" because they are comprised primarily of the elements carbon‚ hydrogen and oxygen. The present experiment will be the synthesis of a familiar organic compound called aspirin. The common chemical name is acetylsalicylic acid. Aspirin‚ the most

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.
