Aspirin Synthesis and Analysis Revised: 12/13/14 • Crush an aspirin tablet and place in a labeled, pre-weighed vial or test tube. Aspirin (acetylsalicylic acid) was synthesized by reacting salicylic acid and acetic anhydride with the aid of phosphoric acid as a catalyst. Abstract: The goal of this experiment was to synthesize aspirin. 11. UNIVERSITY Green fields, Vaddeswaram, Guntur Dist.522502 1 DECLARATION We declare that the project work entitled "ANALYSIS OF ASPIRIN . Your task will be to determine how much aspirin is in the tablet and how much of the inert binder is in the tablet. Patented by Bayer in 1893! H 3 PO 4 Safety • Gloves and safety goggles are mandatory when anyone is performing an experiment in the lab. Aspirin: some background! Aspirin Synthesis . According to the TLC analysis results, the compounds (aspirin, acetaminophen, and caffeine) were successfully isolated from the analgesic (Excedrin tablet). 74 Experiment 5 • Synthesis of Aspirin 5Expt. • Take a small amount of the aspirin tablet and dissolve as much as you can in 3 drops of ethyl acetate. The . In order to determine the purity of the aspirin, it must be characterized through various techniques based on You may work on the in-lab questions, including analysis of provided IR & NMR spectra, at any time during your exam period.
