Abstract:

A process for preparing W, Mo or mixed metal oxides thereof by oxidizing a reduced metal oxide of the formula (NH. sub. m R. sub. 4-m). sub. q. sup. + MO. sub. p where each R is independently C. sub. 1 -C. sub. 20 aliphatic, C. sub. 7 -C. sub. 14 araliphatic or C. sub. 3 -C. sub. 8 cycloaliphatic with the proviso that adjacent R's, together with the nitrogen atom to which they are attached, may form a 5, 6 or 7 membered heterocyclic ring, m is an integer from 0 to 4, q is a number from about 0. 001 to 1/3, M is W or Mo and p is a number from 2 to 3 with aqueous hydrogen peroxide. The so-treated reduced metal oxide is isolated and heated in an oxygen containing atmosphere to form metal oxides of the formula MO. sub. p.
