  • Process for the production of lower alcohols by olefin hydration
    Patent number: 8809600
    Abstract: An improved process for the hydration of C2-C5 olefins to the corresponding alcohols via heterogeneous reactive extraction with ion exchange resin catalysts is provided. The improvements are based on the application of a structured catalytic packing, a simultaneous product extraction in multiple condensed phases for enhancement of the overall alcohol production rate and a simplified product purification procedure.
