Abstract
Alkanes are catalytically oxidized in the absence of ammonia by passing a feed gas including the alkane and oxygen at an elevated temperature over a solid catalyst. The partial pressure of the alkane in the feed gas exceeds 0.70 atmospheres absolute. Examples of the catalytic oxidation are the production of acrolein and methacrolein and acrylic acid and methacrylic acid from propane and iso-butane.
Claims2
A process for the catalytic oxidation or oxidative dehydrogenation of an alkane of 3 to 8 carbon atoms to an aldehyde, in which a feed gas comprising oxygen and the alkane in vapor phase is passed in the absence of ammonia and at a temperature in the range of 350.degree. to 569.degree. C. over a solid oxidation catalyst comprising one of the elements Sb, Mo, W, V and Bi;
- at least one other of those elements and/or at least one of the elements Fe, Sn, U, Ti, Pb, Co, Cu and P;
- and oxygen, and in which the partial pressure of the alkane in the feed gas is in excess of 0.70 atmosphere absolute and the alkane constitutes more than 70% of the feed gas by volume.
