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; wherein each of Rand Ris independently selected from hydrocarbyl and substituted hydrocarbyl radicals having 1 to 20 carbon atoms, or from the groups SOH, NH, OH and NO2, or from the atoms H, F, Cl, Br and I provided that Rand Rcan be linked to one another via a covalent bond; each of Qand Qis independently selected from C, CH, N and CR; each of X and Z is independently selected from C, S, CH, 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 Rcan be any of the entities listed for R. The contacting produces an effluent comprising an oxidized hydrocarbon product and unreacted imide catalyst of said formula 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. |
