Abstract

Process for obtaining a reagent for the flotation of coal by oxidation in the liquid phase of aromatic hydrocarbons with or without unsaturated compounds, characterized in that when subjected to oxidation in liquid phase at atmospheric pressure or overpressure and in the absence of catalysts or with a catalyst, mixtures of aromatic hydrocarbons or technically pure aromatic hydrocarbons with air, oxygen or ozone, a partial oxidation of said hydrocarbons is obtained, obtaining hydroperoxides, aldehydes, alcohols and cetans as oxidation products, which communicate to the hydrocarbons thus treated a great capacity to disperse the air in the pulp, and therefore, convert them into highly active reagents for coal flotation, this activity depending on the degree of oxidation reached, which, for a given oxidation time, depends on the volume of oxygen that passes through the hydrocarbon mass, from the tempe and the structure of the hydrocarbon.
