| 1993 | Invention patented by James H. Jr. Beech, Douglas Miller, Jorge Luis Soto, James A. Stoos, and Albert H. Wu on August 1st, 1993. Abstract: An improved process for production of diisopropyl ether by conversion of hydrocarbon feedstock containing propene, propane and C.sub.2 -- light gas components. The overall process steps include, (optionally) prefractionating fresh feedstock containing propene, propane and C.sub.2 -- light gas components to provide a reactor feedstream rich in propene; contacting the feedstock and water in a catalytic reactor with acidic catalyst under olefin hydration and etherification conditions; and recovering from the catalytic reactor a liquid reactor effluent stream containing diisopropyl ether, isopropanol, water, unreacted propene, propane, oligomer and C.sub.2 -- light gas components. DIPE product containing C.sub.6 + oligomer is recovered by separating the liquid effluent stream in a stripper column, and extracting the DIPE-rich liquid with water. An improved separation process is employed for removing water to provide DIPE liquid product substantially free of water. |
