Use

Ethylene can be removed by passing the gas through a sintered-glass disc into fuming H2SO4 then slowly through a column of charcoal saturated with bromine. Bromine and HBr are removed by passage through firebrick coated with N,N-dimethyl-p-toluidine. The ethane is also passed over KOH pellets (to remove CO2) and dried with Mg(ClO4)2. Further purification is by several distillations of liquified ethane, using a condensing temperature of -195o. Yang and Gant [J Phys Chem 65 1861 1961] treated ethane by standing it for 24hours at room temperature in a steel bomb with activated charcoal treated with bromine. They then immersed the bomb in a Dry-ice/acetone bath and transferred the ethane to an activated charcoal trap cooled in liquid nitrogen. (The charcoal had previously been degassed by pumping for 24hours at 450o.) By allowing the trap to warm slowly, the ethane distils, and only the middle third fraction is kept. Removal of methane is achieved using Linde type 13X molecular sieves (previously degassed by pumping for 24hours at 450o) in a trap which, after cooling in Dry-ice/acetone, is saturated with ethane. After pumping for 10minutes, the ethane is recovered by warming the trap to 25o. (The final gas contains less than 10-4 mole % of either ethylene or methane). [Beilstein 1 IV 108.]
