Method for producing at least one of α, β-unsaturated aldehyde and α, β-unsaturated carboxylic acid
Abstract:
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.
