WebPublished November 1988 Asahi Chemical has built a 60,000 t/yr (132 million Ib/yr) cyclohexanol plant at Mizushima, Japan. The plant produces cyclohexene by partial hydrogenation of benzene followed by hydration of the cyclohexene to cyclohexanol using a process developed by Asahi Chemical. WebThe new applications, divided into two groups as follows: 1) Hydrogenation of benzene (to make cyclohexane), light olefinic streams (Vapidrol Process), edible oils (catalyst formulation); 2) Dimerization/oligomerization of propylene (Dimersol G), butylene (Dimersol X), FCC offgases (Dimersol E).
