ABSTRACT:
In the production of a composite oxide catalyst containing at least Mo tegether with V and (or) Nb, the catalyst precursor is subjected to a thermal decomposition step in which: (1) the precursor is heated in a heat-exchanger type apparatus in which a first space accommodating the precursor and a second space through which a heating fluid flows are partitioned and separated from each other, the heating of the precursor being accomplished through the partitioning; (2) the thermal decomposition is carried out as an atmosphere gas of an oxygen concentration of 0.05 to 5 percent is caused to flow through the first space; and (3) the maximum temperature reached in the thermal decomposition is 300.degree. to 550.degree. C.
