- M.sub.a M'.sub.b O.sub.x
- where
- M is a combination of copper and molybdenum;
- M' is at least one of sodium, potassium, cesium, tin and bismuth;
- a is a number of about 0.1 to 1;
- b is a number of about 0.01 to 0.5 and
- x is the number of oxygen atoms determined by the valence requirement of the other elements present.
- 2. The process of claim 1 where the carboxylic acid is of the formula ##STR4## where R is an inert substituent; and
- n is 0-4.
- 3. The process of claim 2 where n is 0.
- 4. The process of claim 1 conducted in the vapor phase.
- 5. The process of claim 1 where M' is tin or a combination of bismuth and cesium and b is a number of about 0.1 to about 0.3.
- 6. The process of claim 5 conducted in the vapor phase and in the presence of a diluent gas.
- 7. The process of claim 6 where the diluent gas is steam or acetone vapor.
