Abstract
Activity coefficient at 94.8 kPa are evaluated over the entire composition range for the binary mixtures of methylethylketone with 1,2 dichloroethane, 1,1,1-trichloroethane, 1,1,2,2-tetrachloroethane and tetrachloroethylene, through bubble point temperature measurements. A Swietoslawski-type ebulliometer is used for the measurements and the composition versus bubble point temperature measurements are well represented by the Wilson model.
