Patent GB-721915-A (GB)
Title: Oxidation of paraffinic hydrocarbons
Filed: 1952-06-27
Abstract: Oxygen-containing aliphatic compounds of low molecular weight including a substantial proportion of acetic acid are obtained by introducing a paraffinic hydrocarbon containing less than 8 carbon atoms into an oxidation-resistant solvent therefor and oxidizing the dissolved hydrocarbon with gaseous oxygen in presence of a dissolved bismuth compound as catalyst.  The bismuth compound may be a soluble organic salt of bismuth, e.g. the acetate, propionate, butyrate, benzoate or acetyl acetonate, or may be an inorganic salt, e.g. the nitrate or chloride.  The oxidation is preferably carried out at 275 to 450 DEG  F. under a pressure of 200 to 2000 pounds per square inch absolute using oxygen as such or in the form of air or other mixture of oxygen with a diluent gas. Acetic acid is a suitable solvent when oxidizing, for example, propane, n-butane, isobutane or pentane. Other solvents specified are methyl acetate, ethyl acetate, benzene, and diphenyl.  Mixtures of oxidation-resistant solvents may also be employed.  The bismuth compound is preferably used in an amount of between 0.05 and 2 per cent by weight of the solvent.  The process may be carried out batchwise but is preferably carried out in a continuous manner.  In the latter case the hydrocarbon and oxidizing gas may be introduced at a controlled rate into a reaction vessel charged with the solvent containing the catalyst and the vapours issuing from the reaction vessel condensed and allowed to separate into an upper hydrocarbon layer and a lower aqueous layer containing the water-soluble oxidation products, the upper hydrocarbon layer being recycled to the reaction zone, if desired, after separation of any oxidation products dissolved therein.  In an example, bismuth acetate is dissolved in glacial acetic acid in a pressure reactor and normal butane in liquid form is then introduced together with air, the pressure being maintained at 815 pounds per square inch absolute and the temperature at about 168 DEG  C.  The vapours are condensed to form two layers as above and the upper hydrocarbon layer continuously recycled whilst the lower aqueous layer is continuously removed and treated for the recovery of the oxygenated products which comprise mainly acetic acid, only a small amount of formic acid being formed.  Comparative examples are also given to show that when cerium acetate, aluminium nitrate and zinc acetate respectively are employed as catalysts under the same reaction conditions the amount of formic acid formed is appreciably increased.  Other products which may be formed along with acetic and formic acids are acetone, methyl ethyl ketone, methyl alcohol and methyl and ethyl acetates.
