WebApr 1, 2024 · Then treat cyclohexanol with copper(II) and chromium(III) oxides to convert it to corresponding ketone (Dehydrogenation): Benzene could work as a starting material but the reaction might be costly and hectic as the catalyst is not a household item $\ce{^{[2]}}$. WebCyclohexanol is an important precursor in synthesizing intermediates of Nylons and also plasticizers. In this paper, a plantwide reactive-distillation process for the production of cyclohexanol by direct hydration of cyclohexene with water has been studied. Design with excess water is needed to economically increase conversion of cyclohexene to 99.9%. …
