Abstract

A mixture of saturated C1- 3-fatty acids containin mainly acetic acid is obtained by oxidizing paraffin hydrocarbons having more than 2, preferably 4 to 8, carbon atoms, or mixtures thereof, in the liquid phase at a temperature between 140 DEG and 230 DEG C. and under a pressure between 30 and 80 atmospheres with oxygen or oxygen-containing gas, a mixture of the hydrocarbons, their oxidation products and oxygen-containing gas being circulated through a flow reactor with a velocity of flow of at least 50 cm./ second, the residence time of the reaction mixture, per passage through the reactor, being from 10 to 100 seconds, the reaction mixture being separated into liquid and off-gas, between 1 and 15% by volume of the liquid being continuously withdrawn and processed by distillation, and the first runnings and the last runnings of the desired fatty acid fraction being admixed with fresh starting hydrocarbon and oxygen-containing gas and returned to the circulated reaction mixture. Hydrocarbons contained in the off-gas may be recovered by washing with diesel oil, and this then stripped and the hydrocarbons returned to the reaction system. The oxygen-containing gas is preferably used in a proportion such that the off-gas after removal of all constituents condensable up to 20 DEG C. and diesel oil wash contains a maximum of 6% oxygen.
