Latest Patents

Hidefumi Sano holds a patent for a process for the preparation of .epsilon.-caprolactam. This invention provides a method for producing .epsilon.-caprolactam by subjecting cyclohexene to a hydration reaction to obtain cyclohexanol. The cyclohexanol is then subjected to a dehydrogenation reaction to obtain cyclohexanone. Following this, the cyclohexanone undergoes an oxime-forming reaction to yield cyclohexanone oxime. Finally, the cyclohexanone oxime is subjected to a Beckmann rearrangement reaction to produce .epsilon.-caprolactam. Notably, the process controls the methylcyclopentanones contained in the cyclohexanone to be not more than 400 ppm. This method allows for the production of .epsilon.-caprolactam with quality comparable to conventional methods at a lower cost.
