Study of the influence of the ammonium sulfate and sulfuric and hydrochloric acid concentrations and of temperature on the solubility of petroleum sulfoxides in aqueous solutions showed that the solubility of petroleum sulfoxides is in the range 0.1-2.1 g/liter. The solubility of petroleum sulfoxides under conditions of extraction of metals from fluoride-sulfate solutions was determined with the aid of factorial experimental design. The initial and constant solubilities of petroleum sulfoxides were determined. Washing of the sulfoxides with a 600-fold volume of 1.0 M H/sub 2/SO/sub 4/ solution lowers the solubility of petroleum sulfoxides from 1.26-1.02 to 0.12-0.10 g/liter. The conditions for extraction of PSO from aqueous solutions by kerosine were found, and it was shown that under these conditions the extraction of sulfoxides into kerosine reaches 85% in a single stage and more than 96% in three stages.
