摘要

Process for obtaining sodium benzoate by catalytic oxidation of toluene by air, essentially characterized by the passage of a stream of air through a solution of toluene and a catalyst, which may be cobalt oleate, linoleate, as well as also salts of manganese and salts of cobalt and manganese of benzoic acid and paraffinic acid, operating at temperatures between 120º and 175ºC under a pressure of 1.5 to 3.5 atmospheres, recovering from the gases that come off the reaction, part of toluene in an absorption tower filled with active carbon.
