Document Type and Number:

WIPO Patent Application WO/2016/136882

Kind Code:

A1

Abstract:

A method for preparing a catalyst for manufacturing an unsaturated aldehyde and/or an unsaturated carboxylic acid, wherein molybdenum component raw materials are set as only ammonium molybdate and the weight of water for dissolving this is at most 8.5 fold with respect to the weight of the molybdenum included in the ammonium molybdate and bismuth component raw materials are set as only bismuth nitrate and the weight of a nitric acid aqueous solution for dissolving this is at least 2.3 fold with respect to the weight of the bismuth included in the bismuth nitrate, wherein the nitric acid concentration of the nitric acid aqueous solution for dissolving the bismuth nitrate is at least 10 wt%.
