Preparation of superacid catalyst used for synthesis of n-butyl propionate

SO 4 2- /TiO 2 solid superacid catalyst was preparaed, and used for synthesis of n butyl propionate based on the reaction of propanic acid and n butyl alcohol with experimental conditions studied and optimized for preparation, and the catalyst was characterized with TG/DTA, FTIR and XRD. The test results show that this kind of catalyst had better catalytic activity and selective ability on n butyl propionate.
