METHOD FOR MANUFACTURING CATALYST, METHOD FOR MANUFACTURING UNSATURATED CARBOXYLIC ACID, METHOD FOR MANUFACTURING UNSATURATED ALDEHYDE AND UNSATURATED CARBOXYLIC ACID, AND METHOD FOR MANUFACTURING UNSATURATED CARBOXYLIC ACID ESTER
Document Type and Number:
WIPO Patent Application WO/2019/013116
Kind Code:
A1
Abstract:
A catalyst is provided with which a target product can be manufactured with high selectivity. The present invention is a method for manufacturing a catalyst that is used when subjecting unsaturated aldehyde to gas-phase catalytic oxidation using molecular oxygen and manufacturing unsaturated carboxylic acid, the catalyst containing at least molybdenum and phosphorus, wherein the method for manufacturing the catalyst includes a step for exposing a catalyst precursor containing a nitrogen-containing component to a pressure exceeding atmospheric pressure, and firing the catalyst precursor.
