The invention provides a new method for synthesizing ethyl hydrazine dihydrochloride, which takes simple and easily prepared acetyl hydrazine as a raw material, and generates N-acetyl-N'-ethyl hydrazine with bromoethane under catalyst conditions , and then remove the acetyl group under the strong acid condition of hydrochloric acid to obtain the ethylhydrazine dihydrochloride product. The structure of the product is confirmed by 1 H NMR and single crystal, and the method is cheap and easy to obtain raw materials, can greatly reduce the production cost, and is suitable for industrial production. |
