Separation of alkane, alkene and alkyne
The gaseous mixture is passed via ammonical cuprous chloride solution. The alkyne (acetylene) reacts along with and makes a red precipitate. It is filtered. The alkyne or acetylene is recovered by decomposition of the precipitate along with an acid.
The other gaseous mixture is passed through concentrated. Alkene is absorbed. Hydrogen sulphate derivatives is heated at 170oC to reproduce ethene.
The methane/ethane is left behind unreacted.
