  • Co-production of 2-alkanones and phenols
    Patent number: 4329509
    Abstract: A process for the co-production of 2-alkanones having at least five carbon atoms and phenol or a substituted phenol. In the first step, benzene or a substituted benzene is alkylated with an alkyl moiety of at least five carbon atoms to selectively produce the 2-arylalkane isomer. Subsequent oxidation to the hydroperoxide and acid cleavage thereof yields the desired product. The alkylation step is carried out in the presence of a novel class of selective crystalline zeolite materials having pore openings with a major dimension of six to seven angstroms.
