Abstract:
A process for producing alicyclic monoketones, comprising hydrogenating substituted bisphenols represented by the following formula (I) in a solvent in the presence of a palladium/alkali metal catalyst in which palladium and an alkali metal are both supported on a carrier, to obtain alicyclic monoketones represented by the following formula (II); ##STR9##whereinX is a --CH.sub.2 --, --C(CH.sub.3).sub.2 --, --O-- or --SO.sub.2 --;R.sup.1 and R.sup.2 are each independently a hydrogen atom or an alkyl group of 1 to 6 carbon atoms; and m and n are each an integer of 0 to 2 and are the same or different; ##STR10##wherein X, R.sup.1, R.sup.2, m and n in formula (II) have the same meanings as those of X, R.sup.1, R.sup.2, m and n in the formula (I).
