Title:
COMPOSITION FOR CATALYST PRODUCTION, PRODUCTION METHOD OF COMPOSITION FOR CATALYST PRODUCTION, AND PRODUCTION METHOD FOR PRODUCING OXIDE CATALYST
Document Type and Number:
WIPO Patent Application WO/2021/153174
Kind Code:
A1
Abstract:
This composition for catalyst production is used in the production of a vapor-phase catalytic oxidation reaction catalyst or a vapor-phase contact ammoxidation reaction catalyst, wherein the composition for catalyst production is an aqueous solution that contains a niobium compound and hydrogen peroxide and that optionally contains an organic acid, and wherein the molar ratio of the organic acid concentration to the Nb concentration (organic acid / Nb) is 0.00-2.00, and the molar ratio of the hydrogen peroxide concentration to the Nb concentration (hydrogen peroxide / Nb) is 0.01-50.
