研究了酮连氮法制备水合肼 ,并考察了原料次氯酸钠的质量浓度以及氯化钠的含量对合成的影响。试验结果表明 ,次氯酸钠的质量浓度对合成水合肼影响较大 ,而原料中氯化钠的含量对合成水合肼影响不大 ,但对分离提纯操作工艺有一定影响。
The preparation of hydrazine hydrate by ketonic nitrogen method was studied. The effects of sodium hypochlorite mass concentration and sodium chloride content on the synthesis were investigated. The experimental results show that the concentration of sodium hypochlorite has a great effect on the synthesis of hydrazine hydrate, while the content of sodium chloride in the raw material has little effect on the synthesis of hydrazine hydrate, but it has an impact on the separation and purification process.
