摘要
采用稀土改性SO2-4/TiO2固体超强酸催化剂,以肉桂酸、正丁醇为原料,合成肉桂酸正丁酯,实验结果表明,当0.015mol肉桂酸、0.045mol正丁醇和1.5g催化剂一起回流2.5h,酯产率可达92%。
Synthesizing n-butyl cinnamate from cinnamic acid and n-butyl alcohol using solid super acid of rare earth modified SO^(2-)_4/TiO_2.The experiment results show that when 0.015 mol cinnamic acid,0.045 mol n-butyl alcohol and 1.5g catalyst were refluxing for 2.5h and the yield of esterification is up to 92%.
