    • 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 Q2is independently selected from C, CH, N and CR3; each of X and Z is independently selected from C, S, CH2, N, P and an element of Group 4 of the Periodic Table; Y is O or OH; k is 0, 1, or 2; 1 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 formula (I) and the effluent is treated with an aqueous solution of a base to produce an aqueous phase comprising at least part of the unreacted imide catalyst of formula (I) and an organic phase comprising oxidized hydrocarbon product. The organic phase can then be recovered.
    • 在将烃氧化成相应的氢过氧化物,醇,酮,羧酸或二羧酸的方法中,烃在含有通式(I)的环状酰亚胺的催化剂存在下与含氧气体接触, 其中R 1和R 2各自独立地选自具有1至20个碳原子的烃基和取代的烃基,或者来自SO 3 H,NH 2,OH和NO 2基团,或者从原子H,F,Cl,Br和I 并且R 2可以通过共价键彼此连接; Q1和Q2中的每一个独立地选自C,CH,N和CR 3; X和Z各自独立地选自C,S,CH 2,N,P和元素周期表第4族的元素; Y为O或OH; k为0,1或2; 1是0,1或2; m为1至3,R3可为R1列出的任何实体。 接触产生包含氧化烃产物和式(I)的未反应酰亚胺催化剂的流出物,流出物用碱的水溶液处理以产生包含至少部分式(I)的未反应的酰亚胺催化剂的水相, 和包含氧化烃产物的有机相。 然后可以回收有机相。
