ABSTRACT:
This invention provides an improved etherification process 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. An hydrogenation catalyst is used to convert the nitriles to amines so that they can be more easily removed from the alcohol phase.
