    摘要: Disclosed is a process for producing phenol or a substituted phenol and a co-product comprising the steps of (i) contacting a first stream comprising an alkylaromatic compound with a second stream comprising an oxygen-containing gas in the presence of a first catalyst comprising a cyclic imide under conditions to convert at least a portion of said alkylaromatic compound to an alkylaromatic hydroperoxide, (ii) producing an effluent stream comprising said cyclic imide, said alkylaromatic hydroperoxide, and said alkylaromatic compound wherein said effluent stream has an alkylaromatic hydroperoxide concentration of from 10 to 40 wt %; and (iii) contacting in a second reactor at least a portion of said effluent stream with a second catalyst to convert said alkylaromatic hydroperoxide to a product stream comprising phenol and said co-product.

    摘要: A method for manufacturing a ketone includes oxidizing an internal olefin or a cyclic olefin having one carbon-carbon double bond or more at a position other than terminals of a molecule thereof in an amide-based solvent in the presence of water, a palladium catalyst, and molecular oxygen, thereby bonding an oxo group to at least one of the carbon atoms constituting the carbon-carbon double bond, in which the amide-based solvent is represented by the formula in the formula (1), R1 represents an alkyl group having 1 to 4 carbon atoms, R2 and R3 each independently represent an alkyl group having 1 to 4 carbon atoms or an aryl group, and when R1 and R2 are alkyl groups, R1 and R2 may be bonded to each other to form a ring structure.
