A gaseous hydrocarbon mixt. was passed through a liq. barrier consisting of complex-forming metal ions in aq. soln., supported in a semipermeable membrane. to give highly selective sepn. of aliph. unsaturated hydrocarbons. Thus, a mixt. contg. ethylene 41.0, methane 22.3, and C2H6 36.7% had C2H4 content 99.948 % ater permeation at 0.471 ml/cm2 min through a cellulose acetate filter, saturated in 1 mole aq. silver nitrate solution and sandwiched between 2 silicone polycarbonate films.
