摘要：
Improved methods for purification and recovery of individual refrigerants from refrigerant mixtures without chemical destruction of the contaminating refrigerant. Aqueous solutions are employed in extraction methods by relying on differences in water solubilities and partition coefficients at ambient temperatures. All refrigerants can be recovered and the aqueous solutions reused to form a cyclic process. Methods include countercurrent extraction.
