Abstract
Isothermal vapor-liquid equilibria (VLE) have been measured for bromochloro methane + tetrachloromethane or benzene at 298.15 K and 313.15 K, and for 1 -bromo-2-chloroethane + tetrachloromethane or benzene at 313.15 K. Bromochl oromethane + tetrachloromethane shows azeotropic behaviour in the temperatu re range covered. These experimental results, along with our previous ones on excess enthalpies, are interpreted with two group contribution models: D ISQUAC (DISpersive-QUAsiChemical) and modified (Dortmund) UNIFAC (UNIquac F unctional group Activity Coefficients).
