Abstract
The invention concerns a catalytic process for the manufacture of oximes by ammoximation of the corresponding carbonyl compounds, characterized in that the catalyst is a solid composition consisting of silicon, titanium and oxygen, chemically combined with each other, and in that the titanium amount, expressed as TiO.sub.2, ranges from 1 to 95% by weight, the XR diffractogam of said composition being a smooth-trend line (halo), typical of the amorphous solids.
