ABSTRACT OF THE DISCLOSURE The invention relates to a process for the removal of acetylenic compounds from a hydrocarbon stream which comprises the steps of: (a) reacting an alcohol or glycol with the acetylenic compounds in the hydrocarbon stream to produce vinyl ethers, gem-diethers, or mixtures thereof, the reaction taking place in the presence of an acid ion exchange resin catalyst wherein the acid groups have been totally replaced by mercuric ions and ions of alkali or alkali-earth metals; and (b) subjecting the reacted hydrocarbon stream from step (a) to distillation to remove the vinyl ethers, gem-diethers, or mixtures thereof. The acetylenic compounds obtained thereby constitute industrially interesting compounds.
