ABSTRACT:
The present invention relates to a method of preparing a catalyst for the ammoximation of carboxylic compounds, consisting of a synthetic, crystaline and porous material based on silicon and titanium oxides, characterized in that a preformed matrix of amorphous silica is impregnated with an aqueous solution, containing a titanium compound and an organic compound of nitrogen, as a templating agent, and that to the thus impregnated material a zeolitic structure is given by means of a hydrothermal synthesis of usual type, shape and size of the matrix being substantially maintained unchanged.
