| Abstract: | Ti(SO 4) 2/SiO 2 was applied as a catalyst to esterification of butyric acid with n batanol firstly, it has high activity and excellent selectivity as well as no corrosion to the facilities. The optimum reaction conditions were obtained as follows: titanium sulfate supported on SiO 2 10%, butric acid 0.2 mol, n butanol 0.3 mol, the catalyst 0.8 g, reaction temperature 140 ℃, reaction time 60 min. Under the optimum conditions, the rate of esterification was over 99%. |
