In its essentials my process comprises treating petroleum or a fraction thereof containing one or more nitrogen bases with a volatile acid or a nonvolatile acid salt together with a mutual solvent for the acid and hydrocarbon to effect the improved recovery of the nitrogen base¡£It has been postulated that one reason for the comparatively inefficient separation of nitrogen bases from hydrocarbons is because of the poor solubility of the reagents normally employed in the extraction¡£I have found that this difficulty may be overcome by combining with the extractive solvent a mutual solvent which has the effect of increasing the solubility of the extractive solvent in the hydrocarbon resulting in improved recovery of the nitrogen bases¡£
