Three-phase solid--liquid--vapor equilibria of the systems ethane--benzene, ethane--cyclohexane, and ethane--trans-decalin

Pressure-temperature profiles along with liquid compositions and liquid molar volumes for binary systems of the solvent ethane with the solutes benzene, cyclohexane, and trans-decalin are presented for the solid-liquid-vapor loci. The data were taken using cryoscopic techniques over a liquid compositional range extending from solute-rich solutions to solute-lean solutions. The data are pictorialized as the logarithm of composition vs. reciprocal temperature to elucidate the nonideality of the liquid phase. The standard deviations of the liquid compositional data are 1.37 percent for benzene, 1.55 percent for cyclohexane, and 1.53 percent for trans-decalin.
