Production of cyclohexylbenzene hydroperoxide

摘要

In a process for producing cyclohexylbenzene hydroperoxide, cyclohexylbenzene is contacted with oxygen to produce a reaction product comprising cyclohexylbenzene hydroperoxide and unreacted cyclohexylbenzene. The reaction product is then maintained under conditions such that crystals of cyclohexylbenzene hydroperoxide form and separate from the reaction product. The cyclohexylbenzene hydroperoxide crystals are then recovered from the reaction product.

主权项

1. A process for producing cyclohexylbenzene hydroperoxide, the process comprising:
(a) contacting cyclohexylbenzene with oxygen and N-hydroxyphthalimide to produce a reaction product comprising cyclohexylbenzene hydroperoxide and at least a portion of the N-hydroxyphthalimide; (a-1) removing at least a portion of the N-hydroxyphthalimide from the reaction product; (b) after the removing (a-1), treating at least a portion of the reaction product under conditions such that crystals of cyclohexylbenzene hydroperoxide form; and (c) recovering at least a portion of the cyclohexylbenzene hydroperoxide crystals from the reaction product.
