Abstract
A process for preparing saturated carboxylic acids having from one to four carbon atoms by gas-phase oxidation, includes reacting 2-butanone with oxygen over a coated catalyst which is an inert nonporous support body and a catalytically active mixed oxide composition comprising (a) one or more oxides selected from the group consisting of titanium dioxide, zirconium dioxide, tin dioxide and aluminum oxide, and (b) from 0.1% to 1.5% by weight, based on the weight of the component (a) and per m2/g of specific surface area of the component (a), of vanadium pentoxide, applied to the external surface of the support body.
Claims19
A process for preparing saturated carboxylic acids having from one to four carbon atoms by gas-phase oxidation, which comprises
- reacting 2-butanone with oxygen by contact with a coated catalyst, said coated catalyst comprising an inert nonporous support body having an external surface and a catalytically active mixed oxide composition comprising
- (a) at least one oxide selected from the group consisting of titanium dioxide, zirconium dioxide, tin dioxide and aluminum oxide, and
- (b) from 0.1% to 1.5% by weight, based on the weight of the component (a) and per m2/g of specific surface area of the component (a), of vanadium pentoxide,
- applied to the external surface of the support body.
