Abstract
Isothermal vapor-liquid equilibria for hydrogen fluoride (HF) + difluo romethane (HFC-32), HF + 1,1,1,2-tetrafluoroethane (HFC-134a), and HF + 1-chloro-1,2,2,2-tetrafluoroethane (HCFC-124) were measured by the P -T-x method at 283.3 and 298.2 K. Vapor compositions were calculated f rom these results. Among these systems, the HF + HFC-134a and HF + HCF C-124 systems exhibit minimum boiling azeotropes at both temperatures.
