(57) Abstract :
A process for producing sec-butyl benzene comprises contacting a feed comprising benzene and a C4 alkylating agent under
alkylation conditions comprising a temperature of about 110°C to about 150°C with a catalyst comprising at least one molecular sieve
having an X-ray diffraction pattern including d-spacing maxima at 12.4±0.25, 6.9±0.15, 3.57±0.07 and 3.42±0.07 Angstrom. The secbutylbenzene
can be then oxidized to produce a hydroperoxide and the hydroperoxide decomposed to produce phenol and methyl
ethyl ketone.
