    摘要: In a process for oxidizing cyclohexylbenzene, a composition comprising cyclohexylbenzene is contacted with oxygen in at least one oxidation zone under oxidation conditions sufficient to produce at least some (i) cyclohexylbenzene hydroperoxide; (ii) a first byproduct; and (iii) a second byproduct in an effluent. A ratio β is determined according to the following formula: (I) wherein A is the amount of the first byproduct in the effluent and B is the amount of the second byproduct in the effluent. The ratio β is then maintained above a threshold value or adjusted above a threshold value.

    摘要: In a process for oxidizing a hydrocarbon to a corresponding hydroperoxide, alcohol, ketone, carboxylic acid or dicarboxylic acid, the hydrocarbon is contacted with an oxygen- containing gas in the presence of a catalyst comprising a cyclic imide of the general formula (I); wherein each of R 1 and R 2 is independently selected from hydrocarbyl and substituted hydrocarbyl radicals having 1 to 20 carbon atoms, or from the groups SO 3 H, NH 2 , OH and NO2, or from the atoms H, F, Cl, Br and I provided that R 1 and R 2 can be linked to one another via a covalent bond; each of Q 1 and Q 2 is independently selected from C, CH, N and CR 3 ; each of X and Z is independently selected from C, S, CH 2 , N, P and elements of Group 4 of the Periodic Table; Y is O or OH; k is O, 1, or 2; 1 is 0, 1, or 2; m is 1 to 3, and R 3 can be any of the entities listed for R 1 . The contacting produces an effluent comprising an oxidized hydrocarbon product and unreacted imide catalyst of said formula (I) and the effluent is treated with a solid sorbent to remove at least part of the unreacted imide catalyst and produce a treated effluent comprising said oxidized hydrocarbon product. The organic phase can then be recovered.
