Abstract
There is described an improved membrane-liquid barrier system of the type containing complex-forming, silver-containing ion component in an aqueous solution, and an improved process in which the membrane-liquid barrier combination can be employed to separate olefinically-unsaturated hydrocarbons. The membrane is in contact with an aqueous solution having dissolved therein complex-forming silver-containing ions, and further includes small but effective amounts of hydrogen peroxide to retard reduction of the ionic silver to elemental silver.
