1499646 Removing acetylenic compounds from hydrocarbons SNAMPROGETTI SpA 6 July 1976 [8 July 1975] 28110/76 Heading C5E Acetylenic compounds are removed from hydrocarbon mixtures containing them by contacting the mixtures with an organic acid in the presence of an acidic ion-exchange resin, the acidic groups of which have been substantially totally exchanged with both mercuric ions and alkali metal or alkaline earth metal ions, the acetylenes forming an addition compound with the organic acid. The esters formed may be removed by rectification. The preferred acid is acetic acid. The process may be carried out at 20-120‹ C. in the liquid or gaseous phases. The process may be used to purify ethylene, propylene, butadiene or mixtures thereof.
