Abstract:
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. The invention provides a means for stabilizing a Lewis acid catalyst for use in a continuous reaction process wherein the water is present in an amount of up to or equal to 10 vol. % of the organic solvent.

Claim (Index 17):
A continuous flow process for the preparation of one or more esters of lactic acid and 2-hydroxy-3-butenoic acid from a sugar selected from one or more of the group consisting of glucose, fructose, mannose, sucrose, xylose, erythrose, erythrulose, threose and glycolaldehyde, in the presence of a solid Lewis acid catalyst and a solvent comprising an organic solvent and water, wherein the vol. % of water present in the organic solvent is from 0.25 to 10 vol. %, and wherein the solid Lewis acid catalyst is Sn-BEA.
