    摘要： The present invention provides a method for producing an α,β-unsaturated carboxylic acid in high yield. In particular, the present invention resides in a method for producing an α,β-unsaturated carboxylic acid by oxidation of an olefin or an α,β-unsaturated aldehyde with molecular oxygen in liquid phase in the presence of a catalyst containing at least palladium, wherein at least one compound selected from the group consisting of p-methoxyphenol, 4,4′-dihydroxytetraphenylmethane, 1,1,1-tris(p-hydroxyphenyl)ethane, compounds having an N-oxyl group in the molecule and compounds having an N-nitrosyl group in the molecule is caused to be coexistent.

    摘要： Disclosed is a method for producing at least one of an α,β-unsaturated aldehyde and an α,β-unsaturated carboxylic acid from an alcohol in a liquid phase through a simple process. Namely, at least one of an α,β-unsaturated aldehyde and an α,β-unsaturated carboxylic acid is produced by dehydrating and oxidizing an alcohol in a liquid phase at 110 to 250° C. in the presence of molecular oxygen and a noble metal-containing catalyst. Alternatively, at least one of an α,β-unsaturated aldehyde and an α,β-unsaturated carboxylic acid is produced by dehydrating and oxidizing an alcohol in a liquid phase in the presence of molecular oxygen, a noble metal-containing catalyst, and an acidic substance.
