Title: Synthesis of Dioctyl Adipate by Fe_2O_3-SO_4~(2-) Solid Super Strong Acid
Abstract: The synthesis of dioctyl adipate with adipic acid and octanol as reactants and solid super acid Fe2O3-SO42 as catalysts has been studied. The influent conditions of reactants on the yield of tests , such as the activation temperture of catalyst, the amount of catalyst used, the molar ratio of octanol to adipic acid and the reaction time, are investigated. The result shows that the appropriate conditions should be:activation temperture of catalyst: 500℃; weight of catalyst :1.5g( if the weight of adipic acid is 0.1 molar); molar ratio of octanol to adipic acid:3:1; reaction time:2.5h.The yield of ethyl sallcylate is about 85%.
