Study on the synthesis of benzyl acetate catalyzed by SO_4~(2-)/TiO_2 solid superacid

Benzyl acetate was synthesized with benzyl alcohol and acetic acid as raw material and solid superacid SO 2- 4/TiO 2 as catalyst.The factors that have influence on the reaction were investigated.The results showed that the optimal conditions were 1.5 g catalyst and 15 mL cyclohexane(to remove water)with the molar ratio of benzyl alcohol/acetic acid being 1.8:1 and the reaction time being 2.5 h;The yield of benzyl acetate under such conditions was about 86.0%.
