Caprolactam purification resin

In the preparation of caprolactam in the HPO process, the crude caprolactam prepared by cyclohexanone oxime Beckmann rearrangement and aqueous ammonia hydration must contain a large amount of organic impurities and salts such as cerium derivatives. The process uses an ion exchange resin to remove traces of ammonium sulfate and organic impurities from the aqueous caprolactam solution.
Suzhou Bojie Resin Technology Co., Ltd. provides caprolactam purified resin, which has large exchange capacity, convenient regeneration and high mechanical strength. It can effectively remove impurities in caprolactam and purify caprolactam.
