| titleOfInvention | Process for Producing Alkylbenzene Hydroperoxides |
| abstract | In a process for producing alkylbenzene hydroperoxides, a feed comprising (i) sec-butylbenzene, (ii) cumene in an amount greater than 10 wt % of the total feed and (iii) at least one of iso-butylbenzene and tert-butylbenzene in an amount up to 20 wt % of the total feed is contacted with an oxygen-containing gas in the presence of a catalyst comprising a cyclic imide of the general formula (I): n n n n n n n n n n 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 NO 2 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 0, 1, or 2; l 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 is conducted under conditions to convert the sec-butylbenzene and cumene to their associated hydroperoxides. |
