Abstract:Aspirin was synthesized through O-acylating reaction from salicylic acid and acetic anhydride by microwave radiation with sodium acetate as catalyst. Several factors influencing on the reaction yield such as the kind of catalysts,the ratio of salicylic acid to acetic anhydride,the power of microwave radiation, the time of microwave radiation and thc optimum method was gained. The result indicates that microwave synthesis has many advantages including simplification in method, time saving, no pollution and good quality for the sample. The method is suitable for green chemical synthesis in industrial producing.
Keywords:Aspirin  catalyze synthesis  microwave(radiation)
