| 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 |
