Abstract
In a process for the production of tertiary ethers by the reaction of an alcohol and isoalkene, a sidecut stream is selected from the etherification separation zone and recycled back to the etherification reaction zone. When this sidecut stream is characterized by an isoalkene to tertiary ether molar concentration ratio that is greater than the isoalkene to tertiary ether molar concentration ratio of the etherification reaction effluent (which is normally at equilibrium conditions), the conversion of isoalkene to tertiary ether is increased.
