Bubble pressures and saturated liquid molar volumes of binary and ternary mixtures of chlorofluorocarbons and hydrochlorofluorocarbons

Abstract

Laugier, S., Richon, D. and Renon, H., 1994. Bubble pressures and saturated liquid molar volumes of binary and ternary mixtures of chlorofluorocarbons and hydrochlorofluorocarbons. Fluid Phase Equilibria 93; 297-316. The aim of this paper is to present new data for refrigerant mixtures. Bubble pressures and saturated liquid molar volumes were measured at several temperatures for the following binary systems; chlorodifluoroethane-trichlorotrifluoroethane (R142b-R113) trifluoromethane-chlorodifluoromethane (R23–R22), trifluoromethane-dichlorotetrafluoroethane (R23-R114): and the ternary system; trifluoromethane-dichlorotetrafluoroethane-trichlorotrifluoroethane (R23-R114-R113) using a variable volume cell and static isothermal equilibrium method. Data modeling was performed using several cubic equations of state with the present data. The best performance to represent simultaneously vapor pressures and saturated liquid molar volumes of either binary or ternary mixtures was achieved by either the regular or the generalized Trebble-Bishnoï-Salim equation of state (1991).
