| titleOfInvention | Process for recovering caprolactam from aqueous caprolactam product using alkali amino caproate in situ |
| abstract | "PROCESS TO RECOVER CAPROLACTA FROM WATER CAPROLACTA PRODUCT USING IN SITU CAPALATO ALKALI AMINO". The present invention relates to a continuous process for recovering caprolactam from aqueous caprolactam product, said aqueous caprolactam product comprising (i) caprolactam, (ii) impurities, and (iii) water, said process comprising: adding the alkali hydroxide to the aqueous caprolactam product in an amount of not more than 100 mmol alkali hydroxide per kg caprolactam; reacting at least part of the alkali hydroxide added to form the alkali amino caproate to obtain a caproate enriched caprolactam product; and distilling the caproate enriched caprolactam product under reduced pressure. |
