Abstract
An ether is prepared by reacting a selected olefin with an alcohol in a two reaction zone system: in the first reaction zone, the catalyst is dispersed in the liquid phase of the reactants and boiling of the mixture is avoided; in the second reaction zone, the catalyst is in a fixed bed. A cooled recycle stream is fed back to the first stage reactor. The catalyst is a sulfonated ion exchange resin in the acid form.
