Bubble points of the HCl-water-isopropanol and the HCl-water-isopropanol-benzene systems and liquid-liquid equilibria (LLE) of the HCl-water-benzene and the HCl-water- isopropanol-benzene systems were measured at 25-85°C and 30-70°C, respectively. The electrolyte nonrandom two-liquid model proposed by Chen et al. [C.-C. Chen, H.I. Britt, J.F. Boston, L.B. Evans, AIChE J. 28 (1982) 588-596] can satisfactorily correlate bubble points and liquid-liquid equilibria of the present mixed-solvent electrolyte systems over the entire range of temperature and concentrations using only binary adjustable parameters.
