Using conditional test,the 1,2-Cyclohexanedicarboxylic acid diisononyl ester was synthesized from Isononyl alcohol and hexahydrophthalic anhydride by direct esterification.The effects of reaction temperature,reaction time,raw materials mol ratio,and the catalyst dosage on the esterification rate were studied.The proper technological conditions were that the reaction temperature was 230 ℃,reaction time was 4 h,the mol ratio of Isononyl alcohol to hexahydrophthalic anhydride was 2.8,and catalyst dosage was 0.25%(based on hexahydrophthalic anhydride).Experimental results showed that the catalyst had many advantages,such as easy preparation,low cost and high activity.It was a1so non-corrosive and pollution-free to the environment.
