ResumoPURIFICATION OF BIODIESEL.This work describes the results of the purification of methyl biodiesel, obtained by oxidized soybean oil, using different methods.After the ester separation from the glycerin by decanting, the ester was purified each time with distillation, washing with water and adsorption with bauxite, bentonite and attapulgite.The removal of total contamination, unsaponifiable material, concentrations of free glycerin and soap were analyzed in the purified ester phase.The best result of purification was observed with the use of bentonite and bauxite, in the removal of soap and free glycerin respectively.
