Abstract
Process for the purification of benzene and homologous products by formaldehyde, to remove from them impurities such as thiophene, thiol toluene, coumarone, indene and its alkyl derivatives, alkyl benzenes and alkyl naphthenes, thionaphtene, and impurities of analogous type, characterized in that the benzene or homologue of the benzene to be purified is subjected to a condensation operation of the impurities by treatment with formaldehyde in the presence of sulfuric acid as a catalyst.
