Title:
CATALYST FOR PRODUCTION OF UNSATURATED ALDEHYDE AND/OR UNSATURATED CARBOXYLIC ACID, METHOD FOR PRODUCING SAME, AND METHOD FOR PRODUCING UNSATURATED ALDEHYDE AND/OR UNSATURATED CARBOXYLIC ACID
Document Type and Number:
WIPO Patent Application WO/2016/147324
Kind Code:
A1
Abstract:
Provided are: a catalyst which is capable of producing an unsaturated aldehyde and/or an unsaturated carboxylic acid, preferably acrolein and/or acrylic acid, or methacrolein and/or methacrylic acid with high yield; and a method for producing an unsaturated aldehyde and/or an unsaturated carboxylic acid, which uses this catalyst. The inventors of the present invention have found that an unsaturated aldehyde and/or an unsaturated carboxylic acid can be obtained with higher yield by using, as a catalyst for producing an unsaturated aldehyde and/or an unsaturated carboxylic acid, a catalyst that contains molybdenum and bismuth as essential components, while setting the turbidity of a mixture of water and ammonium molybdate, which is used as a molybdenum starting material, to 30 NTU or less.
