| titleOfInvention | A kind of preparation method of hydrazine sulfate |
| abstract | A preparation method of hydrazine sulfate, comprising the following steps: 1) taking a sulfuric acid solution with a concentration of 30-70wt% and placing it in a reactor, controlling the temperature to be 20-80 DEG C, and adding acetazine dropwise to the reactor; 2) After the hydrazine hydrate cannot be detected in the reactor, the material in the reactor is cooled, crystallized and suction filtered to obtain the hydrazine sulfate product. The preparation process of the invention is simple and convenient, the reaction conditions are mild and controllable, the formation of by-products can be effectively avoided, and the obtained hydrazine sulfate has high purity and easy separation. |
