HCID 3283Diethyl Ether溶媒

実験手順

10 mmol of 3-phenylglutaric acid and 30 mmol of acetic anhydride are heated under reflux until they have dissolved completely. After cooling, 3 ml of diethyl ether are added and the precipitate is filtered off and washed with diethyl ether. This gives 3-phenylglutaric anhydride.
