FIELD: chemistry.
SUBSTANCE: described is a redox ammoximation method in which a ketone or aldehyde reacts with ammonia and oxygen in the presence of a catalyst, in which the catalyst is an aluminophosphate-based redox catalyst, having at least two different redox catalytic centres containing atoms of different transition metals selected from Co(III), Mn(III), Fe(III), Ti(IV), Cr(VI), Cu(III), V(V) and Ru(III). Described also is use of oximes obtained using the method described above, particularly cyclohexanone oxime for producing ε-caprolactam.
EFFECT: high output of the ammoximation process.
