    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 R1 and R2 is independently selected from hydrocarbyl and substituted hydrocarbyl radicals having 1 to 20 carbon atoms, or from the groups SO3H, NH2, OH and NO2, or from the atoms H, F, Cl, Br and I provided that R1 and R2 can be linked to one another via a covalent bond; each of Q1 and Q2 is independently selected from C, CH, N and CR3; each of X and Z is independently selected from C, S, CH2, N, P and elements 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 R3 can be any of the entities listed for R1. 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.

    摘要: A process for producing sec-butylbenzene comprises feeding reactants comprising benzene and a C4 olefin to a distillation column reactor having a first reaction zone containing an alkylation catalyst and a second distillation zone, which is located below said first reaction zone and which is substantially free of alkylation catalyst, wherein the ratio of the number of distillation stages in said first reaction zone to the number of distillation stages in said second distillation zone is less than 1:1. Concurrently in the distillation column reactor, the reactants are contacted with the alkylation catalyst in the first reaction zone under conditions such that the C4 olefin reacts with the benzene to produce sec-butylbenzene and the sec-butylbenzene is fractionated from the unreacted C4 olefin. The sec-butylbenzene thereby passes as a liquid phase stream from the first reaction zone to the second distillation zone and the liquid phase stream is withdrawn from the distillation column reactor as bottoms.
