Purification of aqueous glyoxal solutions |
| abstract |
Aqueous glyoxal solutions which contain organic acids are purified by means of a membrane cell comprising two or more compartments by passing the glyoxal solution through at least one of the cell compartments separated from the neighboring compartment(s) by anion exchange membranes and by passing the aqueous solution of a base through at least one of the neighboring compartments. |
