Abstract
A process for removing alkynes from hydrocarbon mixtures, particularly those containing butadiene by reacting the alkynes with hydroxyl group containing organic compounds in the presence of a silver exchanged ion-exchange resin and separating the products formed from the unreacted components of said mixture.
Claims21
A process comprising contacting an alkyne with a C.sub.1 -C.sub.4 monohydric alcohol or mixture thereof under reaction conditions to form an ether, said reactive process occurring in the presence of a catalytic amount of a cation-exchange resin having a plurality of pendant sulfonate groups with silver metal counterions.
A process for etherifying alkynes comprising contacting under conversion conditions an alkyne or mixture thereof with an organic compound containing at least one hydroxyl group in the presence of ion-exchange resin containing silver ions.
A process for the removal of alkynes from inorganic or organic mixtures or combination mixtures thereof comprising contacting under reaction conditions said alkyne-containing mixture with an organic compound having at least one hydroxyl group in the presence of a catalytic amount of a silver exchanged ion-exchange resin and thereafter removing the oxygen-containing products from said mixture.
A process for the removal of alkynes from fluid streams comprising contacting a fluid stream containing a plurality of alkynes with water, or an organic compound having at least one hydroxyl group or mixture thereof under conditions sufficient to convert said alkynes to oxygen-containing products and removing from the reaction mixture the products so formed, said reactive process occurring in the presence of a catalytic amount of a polymeric material having associated therewith silver ions.
