【Abstract】 A focused single-mode microwave synthesis system was used to explore the synthesis of diphenoxymethane/ethane compounds from the reaction of substituted phenol with dichloromethane and 1,2-dichloroethane under solvent-free conditions. The effects of microwave irradiation temperature, time, phase transfer catalyst, alkali type and dosage on the reaction were investigated. Under the optimized experimental conditions, different phenols were selected to react with dichloromethane and 1,2-dichloroethane respectively to synthesize 8 kinds of similar compounds with high yield. The product structure was characterized by melting point determination and infrared spectroscopy.更多还原
