Patent ID: 8779124

Claim:
A redox ammoximation process comprising reacting a C 6 -C 12 cyclic ketone with ammonia and oxygen in the presence of a catalyst to form an oxime, wherein: the catalyst is an aluminophosphate based redox catalyst having the formula (I) M 1 M 2 AlPO-5 (I) wherein M 1 is at least one selected from Co(III), Mn(III), Fe(III), Cu(III), V(V), and Ru(III) having redox catalytic capability; M 2 is at least one selected from Ge(IV), Sn(IV), Ti(IV), and Re(IV); and a proportion of the phosphorous atoms in the M 1 M 2 AlPO-5 type structure are replaced by M 2 atoms.
