PROCESS FOR PREPARING ESTERS OF LACTIC ACID, AND 2-HYDROXY-3-BUTENOIC ACID OR ALFA-HYDROXY METHIONINE ANALOGUES FROM SUGARS |
摘要 |
A continuous flow process for the preparation of one or more esters of lactic acid and 2-hydroxy-3-butenoic acid or α-hydroxy methionine analogues from a sugar in the presence of a solid Lewis acid catalyst and a solvent comprising an organic solvent and water.
