Method for the production of glyceric acid
Glyceric acid compounds of the formula (I)R1R2C(OH)—CR3(OH)—COOX  (I)where R1, R2 and R3 are independently hydrogen, C1-12-alkyl, C6-12-aryl, C7-13-alkaryl or C7-13-aralkyl andX is hydrogen, an alkali metal, an alkaline earth metal/2 or NH4,are prepared by saponification of glycidic acid compounds of the formula (II) where Y is NH2 or OR4 in which R4 is C1-12-alkyl or C7-13-aralkyl,with ring-opening addition of water onto the epoxide ring.Preferably, Y is NH2 and the glycidamide of the formula (II) which is used is prepared by reacting acrylonitriles of the formula (III)R1R2C═CR3CN  (III)with hydrogen peroxide.
