Aspirin purity coursework

Yet if the reaction is heated at too higher temperature, the reflux can fail and gas can escape, causing loss of product. After the crude aspirin product is prepared, it is likely to be impure and needs to be purified by the process of recrystallization, the solvent used for this process is ethanol and water.

To determine the effect of a catalyst and reflux methods on the synthesis of salicylic acid and acetic anhydride. If the variables being tested alter the manufacture conditions, in which the aspirin can be synthesized then it can be proven that they significantly affect the outcome, producing in pure aspirin.

The experiment conducted in this report will synthesize, purify and determine the percentage yield of aspirin. The purity of the product formed will then be determined by a series of tests. Iron (lll) Chloride testing, melting point range and Thin Layer Chromatography tests will all be conducted.
