Abstract

Fatty acids containing 1 to 4 carbon atoms are prepared by oxidizing in the liquid state a paraffinic or naphthenic hydrocarbon or a mixture thereof, said hydrocarbon having a b.p. below 200 DEG C. at standard atmospheric pressure, the oxidation being carried out at a temperature in the range 120-240 DEG C. with a gas containing molecular oxygen in the presence of a co-catalyst containing at least one other metal selected from Na, K, Cu, Mg, Ca, Zn, Cd, Ba, Al, Sn, Pb, Ni and Fe, the total amount of catalyst being in the range 0.001-5% by wt. of the total amount of feed hydrocarbons and the amount of the second metal in the catalyst being in the range 5-10,000% by wt. based on the weight of the Co and calculated as metal. If the feed stocks contain a large amount of sulphur compounds it is desirable to treat the feed stock with conc. H2SO4, AlCl3 and H2 before the oxidation. The reaction product is preferably distilled to give a first fraction containing water and distilling off below 99 DEG C., a second fraction containing the desired fatty acids and water, and third fraction comprising a distillation residue boiling above 170 DEG C., the boiling points being at standard atmospheric pressure. The first and/or third such fractions may be mixed with fresh feed hydrocarbons and the resultant mixture oxidized by the process of the invention. Examples are given.ALSO:A three-component catalyst for the oxidation of hydrocarbons to fatty acids comprises cobalt, barium and sodium, the amount of barium and sodium in the catalyst being in the range 5-10,000% by weight based on the weight of cobalt and calculated as metal. In Example 2 the catalyst comprises 3g. of cobalt naphthenate, 20g. of barium naphthenate and 28g. of sodium naphthenate.
