Abstract
An enhanced method of producing ethers from iso-olefins and alcohols comprises at least one stage of separation of the excess alcohol by an ionic liquid. The ether-hydrocarbon-alcohol effluent treated in said separation stage by the ionic liquid comes from the reaction section and/or from a fractionating column. The separated and condensed alcohol is recycled in the process.
