Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
100 words
A molybdate catalyst of the formula A.sub.a X.sub.b Sb.sub.c Mo.sub.d O.sub.e wherein A is selected from the group consisting of iron or iron and vanadium; X is at least one element selected from the group consisting of aluminum, chromium, cobalt, nickel, copper, bismuth, tellurium, boron, phosphorus, titanium and tungsten; and wherein a is a number from 0.01 to 2, b is a number from 0 to 3; c is a number from 0.1 to 12; d is 12; and e is a number as determined by he combined valence requirement of the elements other than oxygen present in the catalyst.
