摘要：WOx/ZrO2 catalyzed hydration of cyclohexene in sub-critical water was experimentally investigated. The migration of reaction zone into sub-critical water makes it possible to run the hydration in a single liquid phase, and the reaction is free from the limitation of liquid-liquid phase mass transfer to hydration kinetics. The severe hydrothermal environments favor the transformation of surface active sites on WOx-ZrO 2 catalysts to Br?nsted acid centers of stronger acidity, which are highly effective for the hydration of cyclohexene to the desired product cyclohexanol. ? 2011 Elsevier B.V.
