PROCESS FOR PRODUCING PHENOL |
摘要 |
In a process for producing phenol, a mixture of cyclohexylbenzene with from 10 to 90 wt% of a solvent is contacted with oxygen in the presence of a catalyst and under conditions effective to oxidize at least a portion of the cyclohexylbenzene to cyclohexylbenzene hydroperoxide. The catalyst comprises a cyclic imide having an imide group of formula (I): wherein X represents an oxygen atom, a hydroxyl group, or an acyloxy group. At least a portion of the oxygen is dissolved in the mixture and the liquid phase molar ratio of cyclohexylbenzene to oxygen dissolved in the mixture is less than or equal to 20,000: 1. |
