ABSTRACT:
A process for the etherification of isoolefins with alcohols is provided wherein the reaction occurs simultaneously with separation of the ether product and reactants. To assure proper alcohol concentration in a catalytic distillation column, the oxygen concentration derived from alcohol is measured at a point below the catalyst bed and controlled to that which maximizes ether production while preventing alcohol from leaving the reactor with ether product.
