CYCLOHEXANONE PRODUCTION PROCESS WITH IMPURITIES REMOVAL |
摘要 |
<p>The present invention relates to a method for preparing cyclohexanone from phenol in a first process, the first process being a cyclohexanone production process comprising hydrogenating phenol to form a product stream comprising cyclohexanone, phenol and side-products (RSP), including cyclohexanol and undesirable side-product; separating at least part of the product stream having a lower boiling point than cyclohexanone have been removed, into a first fraction comprising cyclohexanone and a second fraction comprising phenol, cyclohexanol and RSP, using distillation; and separating the second fraction into a third fraction, rich in cyclohexanol and comprising RSP, and a fourth fraction, rich in phenol and comprising RSP, using distillation. The invention further relates to an installation for carrying out a method of the invention.</p> |
