ABSTRACT

Vapor liquid equilibrium (VLE) data for binary mixture of sulfuryl chloride and 1,1,1-trifluorotrichloroethane at atmospheric pressure were measured with a double-phase circulation still. The experimental VLE data were correlated well with the Wilson, the nonrandom two-liquid (NRTL), and the universal quasichemical activity coefficient (UNIQUAC) models, respectively. From the correlation results, it is revealed that there is no azeotrope presented in the binary system. All of the experimental VLE data passed the thermodynamic consistency tests performed by the Herington and the Van Ness methods.
