PROCESS FOR PREPARING DIISOPROPYL ETHER Diisopropyl ether is prepared from isopropanol in liquid phase in contact with particular Montmorillonite clay catalysts, optionally in the presence of added propylene. The process is operated in a continuous manner by continuously feeding liquid isopropanol, optionally with added propylene, into a reaction space where the feed contacts the catalyst at 120.degree.C to 250.degree.C for an average contact time of 1 to 120 minutes. Pressure is maintained in the reactor to keep a liquid phase in contact with the solid catalyst. Effluent withdrawn continuously from the reaction space at the feed rate is separated by fractionation to recover diisopropyl ether. |
