ABSTRACT
Oxygen solubility in toluene at temperatures from 298.45 K to 393.15 K and pressures up to 1.0 MPa was measured in an autoclave type phase equilibrium apparatus using the total pressure method. Henry coefficients were derived from the mole fractions at experimental pressures and temperatures. A model based on predictive Soave-Redilich- Kwong (PSRK) equation and modified-Huron Vidal (MHV1) mixing rule combined with the UNIQUAC model was used to predict oxygen solubility in toluene. Both experimental and predicted data are in good agreement, which shows that the oxygen solubility increases with increasing temperature and pressure. The results indicate that the solubilization of oxygen in toluene is an endothermic process. An empirical equation of the Henry coefficient was obtained in this work.
