Abstract

ABSTACT Provided is a catalyst for methacrylic acid production, which has high methacrylic acid yield. A method for producing a catalyst for methacrylic acid production, which comprises: (1) a step for preparing a catalyst starting material liquid A that contains Mo, P and V; (2) a step for preparing a catalyst starting material liquid B that contains a cationic starting material; and (3) a step for preparing a liquid that contains a heteropolyacid having a Keggin-type structure or a salt of the heteropolyacid by adding one of the catalyst starting material liquid A and the catalyst starting material liquid B to the other and mixing together. In the step (3), formulae (i) and (ii) are s a t i s fi e d . 3 . 0 ≤ T/(3√ V) ≤ 13.0 (i) 0.01 ≤ u1 ≤ 1.0 (ii) (In formulae (i) and (ii), V represents the volume [m3] of the catalyst starting material liquid A; T represents the number of addition ports through which the other liquid is added; u1 represents the v o l u m e t r i c fl o w r a t e [ L / m i n u t e ] o f t h e o t h e r l i q u i d a d d e d ; a n d u 1 r e p r e s e n t s t h e a v e r a g e in cases where T is 2 or more.)
