The vapor-liquid equilibrium (VLE) data for four binary and two ternary systems concerning chloroform, benzene, ethanol, and 1-butanol are determined at pressures from 101.3 to 303.0 kPa. The experimental VLE data of binary systems are correlated with the Wilson equation, and those at relevant pressures for ternary systems are predicted with the three-component Wilson equation in which the parameters are taken from the corresponding binary systems. Minimum boiling azeotropes are found for chloroform + ethanol, ethanol + benzene, and benzene + 1-butanol only at 303.0 kPa. In the presence of alcohols, chloroform decomposes at T > 400 K, so the experimental investigation cannot be completed for chloroform + alcohol containing systems at higher pressures.
