Thermophysical properties of water-soda-potash mixtures: experimental data.


Sodium hydroxide-water mixtures were proposed for use in absorption refrigeration since one hundred years ago, because of their favourable vapour pressure characteristics. Unfortunately, they could not have commercial applications for their chemical aggressivity against most of suitable materials. In the recent years, progresses in the materials technology have made feasible the utilization of these compounds. In the present paper a ternary mixture water-soda-potash is considered, with different values of the mole ratio between salts. Vapour pressures, specific heats, kinematic viscosities and densities are experimentally determined. P-T-X diagrams are traced and mixture with most favourable ratios between salts are selected.
