✦ Synopsis

Activity coefficients for the Ar-N,, CZH6-C2H4, and CSHB-CO2 systems are calculated from published vapour-liquid equilibrium compositions at various pressures and temperatures. The activity coefficients are correlated using a two parameter model based on the principles of molecular thermodynamics. The method is used both in the normal liquid and critical regions. The parameters of the model are shown to be reasonably independent of the temperature for the three systems.

The CaO-A1203-CaSO4-H20 system has been investigated at 50°C and 85°C, by calculations of the equilibrium solubility surfaces of AH3, C3AH6, CH, ettringite, monosulphoaluminate and gypsum. The results indicate that monosulphoaluminate becomes a stable phase at elevated temperature. Since ettringite
