摘要：

The thermal properties (heat capacity and heat of mixing) and physical properties (vapour pressure, density, viscosity, surface tension and solubility) of the methanol-lithium bromide-zinc chloride system (1:1 LiBr:ZnCl2 by mass) were measured. The measurements of heat capacity, vapour pressure, density, viscosity and surface tension were carried out at various temperatures and absorbent concentrations. The solubility data were obtained in the temperature range 265.85-343.35 K. The heats of mixing at 298.15 K were obtained for solutions with absorbent concentrations from 0 to 65.8 wt%. Empirical formulae for the heat capacity and the solubility of this system were obtained from experimental data. The vapour pressure data were correlated by an Antoine-type equation. The integral heat of mixing data were correlated by a Redlich-Kister-type equation. Enthalpy-concentration charts for the liquid and vapour phases of this system were constructed on the basis of the observed data.
