ABSTRACT:
An oxygenated organic compound, such as ethanol, is recovered from a dilute aqueous stream thereof by contacting said stream with crosslinked polyvinylpyridine resin or nuclear substituted derivative thereof to effect selective sorption of the compound by said resin. The sorbed compound is thereafter removed from the resin by stripping with an inert gas such as carbon dioxide.
