| titleOfInvention | A kind of azanol, hydroxylamine salt, cyclohexanone oxime combined producing process |
| abstract | The invention discloses a kind of azanol, hydroxylamine salt, cyclohexanone oxime combined producing process.The reaction solution that raw material obtains after Ammoximation reaction, hydroxylamination reaction obtains organic phase through extraction and separation, organic phase prepares product cyclohexanone oxime, or a part of organic phase and a part of product cyclohexanone oxime are hydrolyzed as the raw material of oxime hydrolysis reaction, organic phase is recycled back to oximation reaction device in hydrolyzate, a part of inorganic phase returns azanol oximation reaction device as feedstock circulation in hydrolyzate, and aqueous hydroxylamine solution and hydroxylamine salt is made in another part inorganic phase.Present invention process process is simple, reduce requirement of the Ammoximation reaction to raw material cyclohexanone purity and catalyst performance, the high-quality cyclohexanone oxime product without cyclohexanone is obtained, conducive to the simplification and product quality of downstream caprolactam technology, while obtaining the azanol and azanol product salt of high added value. |
