Hydrogen Peroxide → 2,3-Dihydroxybutanedioic Acid
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Hydrogen Peroxide | HCID 784 | — |
| Reactant | Epoxysuccinic acid | HCID 86022 | — |
| Reactant | Maleic Acid | HCID 444266 | — |
| Product | 2,3-Dihydroxybutanedioic Acid | HCID 875 | — |
Reaction Steps
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.
