Abstract: This invention provides an improved etherification process (20, 30) that reduces the amount of acidic ion-exchange resin catalyst that is deactivated by nitriles. This process uses a water phase to remove nitriles from a hydrocarbon phase followed by an alcohol phase to remove the nitriles from the water phase. A hydrogenation catalyst is used to convert the nitriles to amines so that they can be more easily removed from the alcohol phase. This invention also provides a process to remove nitriles (10, 60). This invention further provides an improved etherification process that reduces the amount of acidic ion-exchange resin catalyst that is deactivated by nitriles. These processes use a water phase to remove nitriles from a hydrocarbon phase followed by a stream, or fuel gas, phase to remove the nitriles from the water phase.

Abstract: A process for the production of a high purity butene-1 product stream (34), having a low concentration of diolefin, and ether (28) for a mixed hydrocarbon stream (14) having a high concentration of diolefin is disclosed. The process includes the steps of diolefin hydrogenation, etherification, product separation and linear olefin isomerization.
