Abstract: PURPOSE:To efficiently remove a surface-active substance in a liquid by treating the subject aqueous solution prepared from a reaction product by the Beckmann rearrangement of a mixture of cyclohexanone oxime with cyclododecanone oxime by combination of specific ion exchange resins. CONSTITUTION:A mixture of cyclohexanone oxide with cyclododecanone oxide is subjected to the Beckmann rearrangement in the presence of sulfuric acid and fuming sulfuric acid. The resultant reaction product is then neutralized with ammonia to obtain a lactam mixture, which is subsequently extracted with a water-immiscible organic solvent, further subjected to back extraction with water and separated into an aqueous phase containing caprolactam and an organic solvent layer containing laurolactam. The obtained aqueous solution of the caprolactam is subsequently treated with a strong acidic cation exchange resin and then a weak basic anion exchange resin, as necessary, further a strong basic anion exchange resin. Regeneration of the ion exchange resins can be carried out with hardly any deterioration in exchange capacity thereof.
