Cyclohexanol is an important intermediate for producing adipic acid and -caprolactame, as well as nylons. Furthermore, cyclohexene directly hydrated to cyclohexanol overcomes the shortcomings of the traditional methods and, is attracting more and more attentions, but due to the solubility of cyclohexene in water, it still suffers from rather low equilibrium conversion and a fairly slow reaction rate. The addition of isophorone can significantly increase the solubility of cyclohexene in the aqueous phase and thus is appropriate as a cosolvent for the direct hydration of cyclohexene to cyclohexanol by extractive distillation. It is known from previous literature that cyclohexene hydration is under medium and high pressure. In this studythe vapor-liquid equilibrium (VLE) data for the vapor-liquid phase equilibrium of binary systems cyclohexene + isophorone and cyclohexanol + isophorone, and ternary systems cyclohexene + cyclohexanol + isophorone, and quaternary systems cyclohexene + water + cyclohexanol + isophorone were measured at 500kPa.
