ABSTRACT:
Waste oils of synthetic lubricants containing fluorine atom are admixed with a solvent containing fluorine atom compatible with the waste oils thereby causing contaminants contained in the waste oils to float up into the upper region on the mixed solution. The solvent containing fluorine atom is removed from the solution of the lower layer by way of evaporation, distillation or the like. The regenerated oils of the synthetic lubricants containing fluorine atom thus obtained are completely colorless and transparent in appearance, and they have properties and performances quite similar to those of the fresh oils.
