MEASUREMENTS OF THE CRITICAL PARAMETERS AND THE VAPOUR-LIQUID COEXISTENCE CURVE IN THE CRITICAL REGION OF HCFC123.

Type of article: Article

Summary

ACOMPARISON OF SOME GENERAL PHYSICO-CHEMICAL PROPERTIES OF R123 WITH R11 IS SHOWN. BY MEANS OF VISUAL OBSERVATION OF THE MENISCUS IN AN OPTICAL CELL, THE CRITICAL TEMPERATURE AND THE CRITICAL DENSITY OF R123 WERE DETERMINED. THE SATURATED LIQUID DENSITIES AND SATURATED VAPOUR DENSITIES NEAR THE CRITICAL POINT WERE ALSO DETERMINED BY OBSERVING THE DISAPPEARANCE OF THE MENISCUS IN THE CELL. THE CRITICAL EXPONENT BETA AND THE SATURATED LIQUID DENSITY CORRELATION WERE SUBSEQUENTLY DETERMINED ON THE BASIS OF THE PRESENT MEASUREMENTS WITH AVAILABLE OTHER DATA.
