ABSTRACT:
Condensed ring polycyclic aromatic beta-alcohols are produced by a process which includes initially reacting a cyclic ketone, such as cyclohexanone with a secondary amine to yield an enamine of the cyclic ketone. The enamine is thereafter reacted with an ethylenically unsaturated ketone, such as methyl vinyl ketone, to yield a condensed ring ketone such as octalone which is thereafter dehydrogenated, preferably with a copper chromite catalyst to yield a pure aromatic beta-alcohol such as beta-naphthol.
