Abstract

A process for the production of diisopropyl ether from high purity propylene without the need of a propane-propylene fractionation column has been developed. The process involves (1) reacting a high purity propylene feedstock and water to produce isopropyl alcohol in a reactor and reacting the isopropyl alcohol with propylene to produce diisopropyl ether in the presence of an acidic ion exchange resin catalyst and a Cdiluent to generate a reactor effluent stream containing at least water, isopropyl alcohol, diisopropyl ether, propylene, and acid, (2) passing the reactor effluent to an acid removal zone to produce an acid-depleted stream, (3) dividing the acid-depleted stream into two portions, (4) recycling a portion to the reactor (5) purging a portion to prevent propane build-up and (6) recovering product diisopropyl alcohol.
