A process for producing phenol and methyl ethyl ketone comprises contacting benzene and a C4 alkylating agent under alkylation
conditions and in the presence of an alkylation catalyst comprising at least one molecular sieve of the MCM-22 family to produce an
alkylation effluent comprising sec-butylbenzene; wherein the contacting is conducted in a plurality of reaction zones and the C4
alkylating agent is supplied to each of the reaction zones. A sec-butylbenzene fraction is recovered from the alkylation effluent and
comprises at least 95 wt% sec-butylbenzene, less than 100 wt ppm of C8+ olefins, and less than 0.5 wt% of isobutylbenzene and tertbutylbenzene.
The sec-butylbenzene fraction is then oxidized to produce sec-butylbenzene hydroperoxide and the hydroperoxide is
cleaved to produce phenol and methyl ethyl ketone.
