Title: Yu Kanda: Innovator in Chemical Processes
Introduction
Yu Kanda is a notable inventor based in Kitakyushu, Japan. He has made significant contributions to the field of chemical engineering, particularly in the production of valuable chemical compounds. With a total of 3 patents to his name, Kanda's work has had a meaningful impact on industrial processes.
Latest Patents
Kanda's latest patents include a method for the preparation of .epsilon.-caprolactam. This innovative process involves several steps, starting with the hydration of cyclohexene to produce cyclohexanol. The cyclohexanol is then subjected to a dehydrogenation reaction to yield cyclohexanone. Following this, cyclohexanone undergoes an oxime-forming reaction to create cyclohexanone oxime, which is subsequently transformed into .epsilon.-caprolactam through a Beckmann rearrangement reaction. Notably, the method controls the presence of methylcyclopentanones in the cyclohexanone to not exceed 400 ppm, ensuring high-quality production at a lower cost.
Another significant patent by Kanda is a method for separating cyclohexene from a mixture containing cyclohexane and benzene. This separation is achieved through extractive distillation using a specific extraction solvent, which enhances the purity of the cyclohexene fraction.
