Abstract
A process for synthesizing di-isopropyl ether (DIPE) by etherification of isopropanol. A multi-stage process can employ propene in mixture with other feedstock materials, such as propane from refinery gas, in a primary hydration stage to produce isopropanol. The isopropanol is enriched between stages to remove water. In the second reaction stage the isopropanol is converted catalytically with large pore acidic zeolite to yield DIPE, which can be separated to recover pure propene.
