Abstract:
      Ferulyl butyrate was synthesized by enzyme catalysis with glyceryl tributyrate and ethyl ferulate as raw materials. The influences of solvent system, lipase type, solvent ratio, molar ratio of substrate(molar ratio of glyceryl tributyrate to ethyl ferulate), reaction temperature and reaction time on the conversion rate of ferulyl butyrate were studied. The results showed that the optimal preparation conditions were obtained as follows: lipase Novozym 435 as catalyst, lipase dosage 50 mg/mL, \[EMIM\] \[TF2N\]-toluene as solvent system, ratio of \[EMIM\] \[TF2N\] mass to toluene volume 1∶ 1, reaction temperature 50 ℃, molar ratio of substrate 3∶ 1 and reaction time 6 d. Under these conditions, the conversion rate of ferulyl butyrate was 76.24%.
