ABSTRACT:
A process for producing phenol and methyl ethyl ketone comprises contacting benzene and a C4olefin under alkylation conditions and in the presence of an alkylation catalyst to produce an alkylation effluent comprising sec-butylbenzene and C8+ olefins. The alkylation effluent is then treated to reduce the amount of said C8+ olefins and produce a treated effluent, whereafter the sec-butylbenzene in the treated effluent is oxidized to produce a hydroperoxide and the hydroperoxide is cleaved to produce phenol and methyl ethyl ketone.
