Document Type and Number:
Japanese Patent JP4995718
Kind Code:
B2
Abstract:
A method for producing an unsaturated aldehyde and an unsaturated carboxylic acid through gas-phase catalytic oxidation of propylene, isobutylene or tertiary butanol, which is a raw material, with molecular oxygen in the presence of a catalyst comprising a complex oxide including molybdenum, bismuth and iron as essential components, by controlling the molar ratio of oxygen to the raw material such that a rate of reaction of the raw material is kept constant in the temperature range of from (TA-15)° C. to TA° C., where TA° C. is the boundary temperature of the activation energy of the catalyst.
