| titleOfInvention | Method for treating and utilizing potassium hydrogen tartrate mother liquor |
| abstract | The invention discloses a method for treating and utilizing potassium hydrogen tartrate mother liquor. The potassium hydrogen tartrate mother liquor takes maleic anhydride as raw material which is oxidized by hydrogen peroxide, alkali is added and the pH value is adjusted at 3.5-3.7, and the mother liquor containing the residual potassium maleic acid as shown in formula I after centrifugally preparing DL-potassium hydrogen tartrate is prepared. The method comprises the following steps: the potassium hydrogen tartrate mother liquor and the hydrogen peroxide are in oxidation reaction under the action of catalyst sodium tungstate, and the DL-potassium hydrogen tartrate as shown in formula II is prepared. The method has the benefits that through recycling the process wastewater, the COD content of the process wastewater is greatly reduced, the waste material is changed into useful material, the DL-potassium hydrogen tartrate is prepared by using the useful components in the process wastewater, and the resource utilization ratio is improved. |
