摘要/Abstract

摘要： 一甲肼是一种重要的液体推进剂，分离反应过程所生成的水是确保一甲肼质量的关键。测定了甲基肼－水（ＭＭＨ－Ｈ２Ｏ）物系在１０１．３３ｋＰａ下的汽液平衡，以及电解质对其汽液平衡的影响。采用盐效应和溶剂化的方法，研究了不同电解质对ＭＭＨ－Ｈ２Ｏ汽液平衡的盐效应。

Abstract: Monomethylhydrazine(MMH)is an important liquid propellant.The water produced in the process of separation and reaction is critical for the quality of MMH.The vapor liquid equilibrium(VLE)of MMH H 2O binary system was measured under 101 3kPa and the influence of the MMH H 2O electrolyte ternary systems was considered.Electrolyte remarkably raised the volatility of MMH and changed the VLE of MMH H 2O binary system.The VLE of MMH H 2O NaCl and MMH H 2O NaOH ternary systems were studied by experiments.Salt effects of electrolytes were correlated with salt effect coeffecient method and solvation method.NaOH had greater effect on MMH H 2O binary system than NaCl.Salt effects of these two electrolytes were compared

Key words: Monomethylhydrazine;Vapor liquid equilibrium +;Salt effect +
