14 ABSTRACT Compounds with two, three or more ethylenic unsaturations (polyunsaturates) are separated from compounds with fewer or no such unsaturations, by contacting a mixture of said compounds with a liquid entrapment medium selective for the polyunsaturates. The entrapment medium containing the polyunsaturates is contacted with an immiscible release medium taking up the polyunsaturates, and normally the polyunsaturates are recovered from the release medium. The entrapment medium and normally also the release medium may then be recycled.
