【 摘 要 】

References(9)Cited-By(1)Solubility of water in typical reformate in a multicomponent system, water + isopropanol + reformate, was studied over a temperature range of 288.15 to 318.15 K. The system studied exhibits type 1 liquid-liquid phase diagram. A simplification of the homogenous multicomponent mixture to a pseudoternary system is recommended. Based on the experimental data, the mutual reformate-water solubility increased as the concentration of isopropanol increased. This observation is very important when assessing both the water pollution by gasoline and sensitivity of gasoline to water. Temperature has no effect on the solubility of reformate in water, but it has a modest effect on the solubility of water in reformate. The experimental results were used to estimate the interaction parameters between each of the three pairs of components for the NRTL and the UNIQUAC equations as a function of temperature. Both equations satisfactorily correlate with the experimental data, however, the UNIQUAC fit was slightly better than that obtained with the NRTL model.
