Abstract: A series xHNF/ZSM-5(where x represents the mass fraction of sulfonic acid resin in the catalyst)composite catalysts were prepared by loading perfluorosulfonic acid resin on ZSM-5 using the impregnation method and applied in the hydration of cyclohexene to produce cyclohexanol. The physicochemical properties of corresponding catalysts were studied by BET, XRD, TEM, and Py-IR. In addition, the influence of reaction condition was also investigated in this work. It was found that with reaction temperature of 125 ℃, 0.4 MPa of nitrogen pressure and the reaction time of 120 min, a 12.9% cyclohexene conversion with the selectivity of cyclohexanol over 99% could achieved with 20HNF/ZSM-5, which is the optimal catalyst in this reaction. Meanwhile, the conversion rate of cyclohexene remained above 10% for the 20HNF/ZSM-5 catalyst with five cycles, indicating its excellent stability during reaction.
