The technical problem of purifying a hydrocarbon stream by removing alkyne type impurities, in particular of the acetylene type, is solved by carrying out an addition reaction with alcohol or glycol on these impurities with the aid of an acidic ion exchange resin, in which the acidic groups are totally exchanged either with mercuric ions or with alkali metal or alkaline earth metal ions, also producing vinyl ethers and geminal diethers, which are of industrial interest. |
