Abstract

A process to prepare acetic acid by oxidation with oxygen or with oxygen-containing gases, of one or more unsaturated hydrocarbons having 4 carbon atoms, characterized by carrying out the reaction with an amount of hydrocarbon between 0.5 and 10% by volume, with respect to the reaction mixture, with an amount of oxygen between 5 and 40% by volume, with respect to the reaction mixture, at a temperature of 150º to 400ºC, for a contact time between 0.1 and 20 seconds, and in the presence of a catalyst composed of molybdenum, tin, oxygen and, optionally, also vanadium, activated by heating to a temperature between 350º and 600ºC, and in which you provide the atomic proportions between (see formula) are expressed by the empirical formula (see formula) where, being a + b + c = 100, a varies from 5 to 90, b varies from 5 to 80 and c varies from 0 to 90.
