Enzymatic method for preparing glyceryl butyrate
An enzymatic method for preparing glyceryl butyrate, comprising: (1) carrying out an esterification reaction between n-butyric acid and glycerol using lipase as a catalyst, ethyl acetate and/or ethyl formate as an additive; (2) separating the reaction product, recovering the additive by distillation under reduced pressure to obtain glyceryl butyrate. The invention uses lipase as a catalyst to catalyze the esterification reaction of n-butyric acid and glycerin at normal temperature and normal pressure, reduces the energy consumption of the reaction. Also, the reaction condition is mild, no side reaction happens, and no water-carrying agent is used. In addition, the additive increases the catalytic efficiency of the lipase and the conversion rate of butyric acid.
