Abstract: DIENES ARE SEPARATED FROM ORGANIC MIXTURES COMPRISING DIENE AND ALKENE HAVING ONE DOUBLE BOND BY CONTACTING THE MIXTURE AGAINST ONE SIDE OF A POLYMERIC PERMEATION MEMBRANE, THE MEMBRANE HAVING A TRANSITION METAL MOLECULARLY DISPERSED THEREIN AND WITHDRAWING ON THE OTHER SIDE OF THE MEMBRANE A VAPOROUS MIXTURE HAVING INCREASED DIENE CONCENTRATION. EXEMPLARY OF THE ORGANIC MIXTURE IS A MIXTURE OF BUTADIENE AND BUTENE. EXEMPLARY OF TRANSITION METAL IS SILVER AS ELEMENTAL SILVER AND AS SILVER TETRAFLUOROBORATE.

Abstract: A MONOALKENE, SUCH AS STYRENE OR HEXENE, IS SEPARATED FROM ORGANIC MIXTURES COMPRISING SAID ALKENE AND ANOTHER ORGANIC COMPONENT OR COMPONENTS BY CONTACTING SAID MIXTURE UNDER PREVAPORATION PERMEATION CONDITIONS AGAINST ONE SIDE OF A POLYMERIC, PERMEATION MEMBRANE, THE MEMBRANE HAVING A TRANSITION METAL MOLECULARLY DISPERSED THEREIN AND WITHDRAWING ON THE OTHER SIDE OF THE MEMBRANE A VAPOROUS MIXTURE HAVING A HIGHER CONCENTRATION OF ALKENE. THE TRANSITION METAL IS IN AN OXIDATION STATE AND IN A FORM WHICH PERMITS CHEMICAL INTERACTION WITH THE MONOALKENE. EXEMPLARY OF TRANSITION METAL IS SILVER AS ELEMENTAL SILVER AND AS SILVER TETRAFLUOROBORATE.

Abstract: DIENES SUCH AS BUTADIENE AND ISOPRENE ARE SEPARATED FROM ORGANIC MIXTURES CONTAINING SAME BY CONTACTING THE MIXTURE AGAINST ONE SIDE OF A POLYMERIC MEMBRANE AND WITHDRAWING AT THE OTHER SIDE A VAPOROUS MIXTURE HAVING INCREASED DIENE CONCENTRATION. THE POLYMER MEMBRANE IS AN ACRYLONITRILE CONTAINING POLYMER WHICH IS (1) A COPOLYMER OF ACRYLONITRILE OR (2) A POLYMER BLEND CONTAINING ACRYLONITRILE POLYMER. EXEMPLARY OF THE POLYMER MEMBRANES ARE COPOLYMERS OF ACRYLONITRILE AND A STYRENE, VINYL ACETATE AND N-VINYLPYRROLIDONE AND BLENDS OF POLYACRYLONITRILE AND POLYSTYRENE, POLYVINYL ACETATE AND POLYVINYLPYRROLIDONE. EXEMPLARY OF THE ORGANIC MIXTURES IS A MIXTURE OF BUTADIENE AND BUTENE.
