Abstract

Alpha dicarbonyl compounds are obtained by oxidising, in the liquid phase, carbonyl compounds, which contain a methylene group adjacent to the carbonyl group, with ozone in presence of a selenium catalyst e.g. selenium dioxide or elemental selenium. The reaction mixture may contain an inert solvent or diluent e.g. water, and the oxidation may be effected at -5 DEG to +90 DEG C. Carbonyl compounds which may be used in the process include methyl ethyl ketone, diethyl ketone, methyl benzyl ketone, cyclopentanone, and methyl cyclohexanone. Aldehydes of the type -CH2-CHO may also be used. Examples describe the production of diacetyl from methyl ethyl ketone, and of cyclohexane-1,2-dione from cyclohexanone, (adipic acid being also obtained).
