【Abstract】 In this paper, the clean synthesis of adipic acid is reported. This environmentally benign synthesis of adipic acid involves in the direct oxidation of cyclohexene catalyzed by Na 2WO 4·2H 2O with aqueous 27.5% hydrogen peroxide using alkyl ammonium sulfate as phase transfer agent. The results show that dodecylammonium sulfate, tri n octylammonium sulfate can be used as efficient phase transfer agents for this reaction under refluxing temperature. It is demonstrated that the efficiency of industrial pure dodecyl tertiary ammonium sulfate and octadecyl tertiary ammonium sulfate is lower that that of dodecylammonium sulfate and tri n octylammonium sulfate. After the reaction is stopped, the homogeneous solution was cooled to 5?℃ for 12 h. The collection of the crystalline product by filtration followed by drying in air produced colorless, analytically pure adipic acid.更多还原
