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%. … WebThe selectivity and activity of gold-catalysts supported on graphite and graphene have been compared in the oxidation of cyclohexene. These catalysts were prepared via impregnation and sol immobilisation methods, and tested using solventless and radical initiator-free reaction conditions. The selectivity of these catalysts has been directed towards …

WebThe purpo se of this lab is to prepare cyclohexene by dehydrating cyclohexanol. D ehydration of al-cohol removes water (H-OH) group from alcohols to produce alkenes. The first s tep in this mecha-nism is protonation of the alcohol group by the acid. T he second step is the loss of water to form the. WebThe dried solution is then fractionally distilled to produce purified cyclohexene. To achieve optimal separation, the distillation must be done at a slow steady rate. To ensure that the …
