Cyclohexene to benzene
WebThe possibility of using cyclohexene as a feedstock has lately become an option because of recent improvements in the partial hydrogenation of benzene to cyclohexene in the Asahi process . The higher reactivity of cyclohexene allows it to be oxidised at lower temperatures by oxidants such as O 2 and hydrogen peroxide, and therefore avoids N 2 … WebThe product is cyclohexane and the heat of reaction provides evidence of benzene's thermodynamic stability. Substituted benzene rings may also be reduced in this fashion, and hydroxy-substituted compounds, such as phenol, catechol and resorcinol, give …
