Соединения с двумя, тремя или более этиленовыми ненасыщенностями (полиненасыщенные) отделяют от соединений с меньшей ненасыщенностью или без нее путем контактирования смеси указанных соединений с жидкой уносящей средой, селективной для полиненасыщенных. Уносящую среду, содержащую полиненасыщенную, контактируют с несмешивающейся выделяющей средой, растворяющей полиненасыщенные, и обычно полиненасыщенные извлекают из выделяющей среды. Уносящую среду и обычно также выделяющую среду затем рециклизуют.Compounds with two, three, or more ethylenic unsaturations (polyunsaturated) are separated from compounds with less or less unsaturation by contacting a mixture of these compounds with a liquid, polyunsaturated selective medium. The carrying medium containing polyunsaturated is in contact with an immiscible release medium dissolving polyunsaturated and usually polyunsaturated is recovered from the release medium. The entrainment medium and usually also the recovery medium is then recycled.
