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

  • 摘要: 以固体超强酸 SO2 - 4 / Ti O2 为催化剂 ,乙酸和苄醇为原料合成乙酸苄酯 ,并考察了影响反应的因素 .结果表明 :醇酸比为 1 .8∶ 1 ,催化剂用量为 1 .5 g,带水剂环己烷用量 1 5 ml,反应时间为 2 .5 h是最适宜的反应条件 ,酯化率达 86.0 %
    Abstract: 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%.
