Reaktionsschritte
Thus free maleic acid is reacted in aqueous solution with hydrogen peroxide in the presence of alkali tungstates or molybdates, the intermediate epoxysuccinic acid formed hydrolyzed by boiling and then the racemic acid formed crystallized out of the hydrolysis solution, see Church and Blumberg, "Ind. Eng. Chem.", Vol. 43 (8) pages 1780 to 1786. The mother liquor of the racemic acid crystallization is again returned into the reaction step.
