Lab Report on the Synthesis and Recrystallization of Aspirin. Scheme SM 9.2.3.1- Reaction scheme for the synthesis of phosphonium salt ].Benzoic acid can be prepared in the home lab through the oxidation of toluene using Potassium (ii) The hydrogen sulfate ion formed in Step (a) (i) removes a proton from the intermediate, regenerating the aromatic ring and the sulfuric acid catalyst. In the first part, the purpose was to find the solubility of the four compounds, anthracite, resorcinol, benzoic acid, and 4-amino-1-napthalenesulfuric acid using three different solvents, water, toluene, and n hexane. My Kitasato (also known as Buchner Flask, Vacuum Flask or Filter Flask) was KIA (killed in action). Benzoic acid is also present in various products including sauces, jams, jellies and candied fruits. However, it might be a good source of Benzoic Acid if you cant find it anywhere.
