Vapor Pressure Measurement and Correlation of 2-Methyl-Butanol Acetate Containing Calcium Chloride

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.
