Abstract

THE PRESENT INVENTION PROVIDES A METHOD FOR PRODUCING E-CAPROLACTAM, WHICH COMPRISES SUBJECTING CYCLOHEXENE TO A HYDRATION REACTION TO OBTAIN CYCLOHEXANOL, SUBJECTING THE CYCLOHEXANOL TO A DEHYDROGENATION REACTION TO OBTAIN CYCLOHEXANONE, SUBJECTING THE CYCLOHEXANORIE TO AN OXIME-FORMING REACTIONN TO OBTAIN CYCLOHEXANONE OXIME, AND SUBJECTING THE CYCLOHEXANONE OXIME TO A BECKMANN REARRANGEMENT REACTION TO OBTAIN E-CAPROLACTAM, WHEREIN METHYLCYCLOPENTANONES CONTAINED IN THE CYCLOHEXANONE SUBJECTED TO THE OXIME-FORMING REACTION ARE CONTROLL.ED TO BE NOT MORE THAN 400 PPM. ACCORDING TO THE PRESENT INVENTION, IT IS POSSIBLE TO PRODUCE E-CAPROLACTAM HAVING A QUALITY NOT INFERIOR TO CONVENTIONAL QUALITY AT A LOW COST.
