Abstract
In a process for oxidizing a hydrocarbon to the corresponding hydroperoxide, alcohol, ketone, carboxylic acid or dicarboxylic acid, a reaction medium comprising a 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 Rand Ris independently selected from hydrocarbyl and substituted hydrocarbyl radicals having 1 to 20 carbon atoms, or from the groups SOH, NH, OH and NO, 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 an element of Group 4 of the Periodic Table; Y is O or OH; k is 0, 1, or 2; l is 0, 1, or 2; m is 1 to 3; and Rcan be any of the entities listed for R. The contacting is conducted under conditions such as to maintain the concentration of both water and organic acids in the reaction medium below 50 ppm.
