Purification of cyclohexene
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%. … Webfluxes for benzene and cyclohexene. It should be noted that, for short reaction times, the rate of diffusion may not keep up with the amount of cyclohexene and cyclohexane formed over the metal surface, thus giving rise to small organic droplets that leave the stagnant water layer around the catalyst to coalesce (. 4 and )
