ABSTRACT
Isothermal vapour liquid equilibrium was measured for dimethylsulphide + 1-butene (312.58 K), dimethylsulphide + cis-2-butene (312.59 K), dimethylsulphide + trans-2-butene (317.30 K), dimethylsulphide + 2-methylpropene (312.60 K), dimethylsulphide + n-butane (317.41 K) and dimethylsulphide + 2-methylpropane (307.86 K) with the static total pressure method. The experimental data were correlated with Legendrepolynomial and the Wilson activity coefficient models. All six binary systems exhibited positive deviation from Raoult s law.
