Boiling temperatures at 94.6 kPa, over the entire composition range are measured for the binary mixtures, formed by acetonitrile with 1,2,-dichloroethane, 1,1,1-trichloroethane, 1,1,2,2-tetrachloroethane, trichloroethylene and tetrachloroethylene, making use of a Swietoslawski type ebulliometer. The liquid phase composition versus temperature measurements are found to be well represented by the Wilson model.
