ISOTHERMAL VAPOR-LIQUID-EQUILIBRIA FOR THE SYSTEMS 1-CHLORO-1,1-DIFLUOROETHANE PLUS HYDROGEN-FLUORIDE, 1,1-DICHLORO-1-FLUOROETHANE PLUS HYDROGEN-FLUORIDE, AND CHLORODIFLUOROMETHANE PLUS HYDROGEN-FLUORIDE

Isothermal vapor-liquid equilibria for the three binary systems (1-chl
oro-1,1-difluoroethane + hydrogen fluoride, 1,1-dichloro-1-fluoroethan
e + hydrogen fluoride, and chlorodinuoromethane + hydrogen fluoride) h
ave been measured. The experimental data for the binary systems are co
rrelated with the NRTL equation with the vapor-phase association model
for the mixtures containing hydrogen nuoride, and the relevant parame
ters are presented. All of the systems form minimum boiling heterogene
ous azeotropes.
