| 摘 要： | The CaCl2 solubility in 2-methyl-butanol acetate and the vapor pressure of 2-methyl-butanol acetate containing CaCl2 were measured in the range of 90-135°C and from very low salt concentration to saturation.The experimental data were correlated with two equations,a modified Antoine equation with the dissolved salt taken into account and a nonrandom two liquid-electrolyte(e-NRTL)model.Both models are in good agreement with the experimental data.This study provides essential physical data for further investigation of vapor-liquid equilibrium system containing salt.

The experimental data were correlated with two equations, a modified Antoine equation with the dissolved salt taken into account and a nonrandom two liquid-electrolyte (e-NRTL) model. Both models are in good agreement with the experimental data. This study provides essential physical data for further investigation of vapor-liquid equilibrium system containing salt. |
