Vapor–liquid equilibrium measurements of dimethylsulfide, +ethanol, +dimethylether, +methylacetate with a static total pressure method

•Three isothermal VLE of dimethylsulfide+ethanol at 350.4K, +dimethylether at 336.7K, +methylacetate at 350.3K were measured with a static total pressure apparatus.•The Barker method was used to reduce the experimental data P, T, z data into P, T, x, y data.•The parameters of Legendre polynomial and Wilson liquid activity coefficient model were optimized.•All systems exhibited positive deviation from Raoult's law.•The dimethylsulfide+ethanol system showed azeotropic behavior.
