乙酰肼合成新工艺研究

Study on the New Synthetic Technology of Acetic Acid Hydrazine

在无溶剂条件下用乙酸乙酯和水合肼反应制备乙酰肼．探讨了乙酸乙酯的浓度、反应温度对收率的影响．反应时间由７０ｈ减少到７ｈ．

In the absence of solvent by using EtoAc and N2 H4. H2O to prepare acetic acid hydrazine. The influences of concentration of EtoAc and the reaction temperature to the yield have been investigated. The reaction time is reduced from 70h to 7h.
