Method for producing oxide catalyst, and method for producing unsaturated nitrile

Abstract

There is provided a method for producing an oxide catalyst to be used for production of an unsaturated nitrile, the method including a step (a) of preparing an aqueous mixed liquid (A) containing Mo, V and Sb, a step (b) of mixing the aqueous mixed liquid (A), a carrier component and a Nb raw material at 20° C. or more and 80° C. or less to obtain an aqueous mixed liquid (B), a step (c) of drying the aqueous mixed liquid (B) to obtain a dried powder, and a step (d) of calcining the dried powder to obtain an oxide catalyst, wherein the aqueous mixed liquid (B) has a solid metal component concentration of 2.0 to 8.0% by mass.
