  • Publication number: 20190276861
    Abstract: 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.

  • Patent number: 8380211
    Abstract: A CS domain call terminating system, includes a routing-controlled determination module that determines a call which has been subject to routing control in accordance with information carried in a received call initiation message. The routing-controlled determination module sends routing-controlled information of the call to a subsequent call flow control module, and the subsequent call flow control module determines and executes a subsequent call flow of the call in accordance with the received routing-controlled information. A network entity can obtain the routing-controlled information of the call during CS domain call termination of the invention, thereby avoiding repeated routing control and an indefinite subsequent call flow in the CS domain call terminating flow.
