Vapour-liquid equilibrium and densities of RE-143a, RE-218 mixtures as R12 or R22 alternatives.

Author(s) : KUL I., DESMARTEAU D. D., BEYERLEIN A. L.

Summary

The vapour pressures of the RE-143a/RE-218 mixture were measured over the entire concentration range for temperatures starting from well below their boiling points up to their normal boiling points. The mixtures form an azeotrope at 0.5 RE-143a mole fraction with a normal boiling point of -30 °C, a critical temperature of 87.9 °C and a critical mixing temperature of well below -70 °C. The vapour pressure of the azeotropic mixture was measured up to the critical point.
