Title: Study on teaching experiment for green synthesis of adipic acid
Abstract: Adipic acid was synthesized by Na2WO4-catalyzed oxidation of cyclohexene with 30% hydrogen peroxide in the presence of HSO4 as a phase transfer catalyst(PTC).After the reactants are heated at 82~98℃(refluxing temperature) for 1 h,it is observed that the most excellent isolated yield of adipic acid is from 48.6% to 68.6%.Sodium tungstate catalyst and phase transfer catalyst of HSO4 can be reused.Compared with the nitric acid or potassium permanganate oxidation traditional process,which generates the serious environmental pollution,has long time of reaction and process large quantities of waste residue,this is a feasible and green chemical process to prepare adipic acid in teaching experiment.
