Document Type and Number:
WIPO Patent Application WO/2020/140309
Kind Code:
A1
Abstract:
The present invention provides a method for preparing a 3-hydroxybutyrate amino acid salt compound, comprising: (1) adding ethyl 3-hydroxybutyrate or methyl 3-hydroxybutyrate into a reaction vessel, taking water as a solvent, adding a base catalyst, and hydrolyzing ethyl 3-hydroxybutyrate or methyl 3-hydroxybutyrate under the effect of the base catalyst to obtain 3-hydroxybutyrate; and (2) adding 3-hydroxybutyrate into the reaction vessel, adding ethyl alcohol as the solvent, then adding natural amino acid, and enabling 3-hydroxybutyrate and natural amino acid to react for 12-24 hours under the temperature at 30-80°C to obtain the 3-hydroxybutyrate amino acid salt compound. According to the present invention, some purification processes are omitted, the operation is convenient, and raw materials are saved. In the mode of salifying in ethyl alcohol according to the present invention, reaction is more thorough, reaction time is saved, energy consumption and material loss are reduced, product yield is increased, and production costs are greatly saved.
