| Abstract: | Butyl cinnamate is synthesized from cinnamic acid and butyl alcohol using nanometer complex tungstophosphoric acid as catalyst.The results show that nanometer complex tungstophosphoric acid is a good catalyst for synthesizing butyl cinnamate.The yield of butyl cinnamate is up to 94% when molar ratio of cinnamic acid to butyl alcohol is 1∶ 2.0,amount of catalyst is 1.2g/0.05mol cinnamic acid,water-carrying agent is 10 mL,and reaction time is 100min. |
