Ube City—Ube Industries has decided to adopt a new manufacturing process for cyclohexanone at its Ube chemical factory in Ube City, Yamaguchi Prefecture, Japan, aiming to further expand its nylon 6 business. The new process produces cyclohexanone, which Ube uses mainly to produce caprolactam, through selective hy-drogenation of phenol. It offers several advantages over the existing manufacturing process, including a streamlined process, downsize equipment and higher yields of cyclohexanone from raw materials. The process also consumes less steam and electricity.
