| titleOfInvention | Synthesis method of hydrazino ethyl acetate hydrochloride |
| abstract | The invention discloses a synthetic method of hydrazino ethyl acetate hydrochloride, which comprises the following processing steps: s1, reacting glyoxylic acid ethyl ester serving as an initial raw material with hydrazine hydrate in a solvent for 30 min-5 h in a pressure kettle to prepare hydrazonoethyl acetate; s2, after the reaction of S1 is finished, adding a catalyst into the reaction solution, and reacting at the reaction temperature of 20-100 ℃ for 0.5-24 hours to obtain hydrazino ethyl acetate; s3, and finally salifying to obtain the target product, namely, the hydrazino ethyl acetate hydrochloride. The reagents and solvents used in the method are in conventional industrial specifications, are suitable for industrial mass production, have little environmental pollution, high operation safety, simple and easy post-treatment, can not generate a large amount of three wastes, and have high yield and low cost. The two-step reaction is finished in one pot, and the production is convenient. |
