Hydrogen solubility was measured for four equimolar binary solvent mixtures, benzene + toluene, cyclohexane + methylcyclohexane, benzene + methylcyclohexane and cyclohexane + toluene, and an equimolar quaternary, benzene + cyclohexane + methylcyclohexane + toluene, in the pressure range from 1.077 to 4.580 MPa at 303.15 K. The hydrogen solubility increased linearly with the pressure for all systems. The binary interaction parameters, in a mixing rule of Peng–Robinson (PR) equation of state, were determined for benzene + toluene and cyclohexane + methylcyclohexane from the vapor–liquid equilibrium data of literature, and that for benzene + methylcyclohexane and cyclohexane + toluene from the hydrogen solubility data in the binary solvent mixture. Using the optimized binary interaction parameters, PR equation well predicted the experimental data for the quaternary.
