Abstract
Process for the solvent extraction of liquids mutually immiscible with each other and having different specific gravity, in which both the mother liquor and the solvent(s) are dispersed in a gas or vapour, thereafter the disperse state of the system is terminated by condensation, and the immiscible phases are separated from each other.
