摘要
以肉桂酸和正丁醇为原料 ,S2 O82 -/TiO2 型固体酸作催化剂 ,催化合成了肉桂酸正丁酯。确定了最佳酯化反应条件 :肉桂酸用量为 0 0 2mol ,肉桂酸与正丁醇摩尔比为 1∶2 5 ,催化剂用量 0 8g ,反应时间 90min ,在此条件下酯化率可达 98 4 8%。
The synthesis of n-butyl cinnamate from cinnamic acid and n-butyl alcohol using S 2O 8 2- /TiO 2 solid acid as catalyst was studied.The optimum synthesis conditions were determined as follows: amount of cinnamic acid 0.02 mol , molar ratio of cinnamic acid to n-butyl alcohol 1∶2.5,amount of catalyst 0.8 g ,reaction time 90 min .The yield of n- butyl cinnamate was up to 98.48 % under these conditions.
