Abstract
Method of preparing benzoic acid, comprising the oxidation of a liquid monoalkylated benzene, for example toluene, with oxygen or a gas containing it, for example air, in the presence of a polyvalent heavy metal catalyst, preferably a cobalt salt of an acid organic, characterized in that the oxidation is carried out using benzoic acid as sole initiator for the reaction, the benzoic acid being initially present in a proportion of 60% by weight at most, based on the total weight of the reaction mixture.
