Abstract
A process for the production of beta-isophorone from alpha-isophorone, comprising the steps of: PA0 (i) heating alpha-isophorone in the presence of an isomerization catalyst, said catalyst comprising a metal acetylacetonate, wherein said metal is selected from the group consisting of aluminum and the metals of Groups IVB, VB, VIB, VIIB and VIIIB of the periodic table, to produce beta-isophorone, and PA0 (ii) isolating said beta-isophorone.
