| Abstract: | Dibutyl adipae is synthesized by the esterification of adipic acid with n-butanol in the presence of stannic chloride pentahydrate. The experimental results indicated that stannic chloride pentahydrate exhibited high catalytic activity for the esterification reaction. The effect of molar ratio of adipic acid to n-butanol and the amount of stannic chloride pentahydrate catalyst on the yield of dibuty adipate have been investigated. The yield of the ester is 96.9% under the selected reaction conditionsn(adipic acid)∶n(n-butanol)∶n(SnCl4·5H2O)＝1∶8∶0.114, refluxing for 60min]. |
