In process for the production of diisopropyl ether, a propylene-containing stream is contacted with isopropyl alcohol in a first stage in the presence of a catalyst under conditions to produce an effluent stream comprising diisopropyl ether. At least a portion of this effluent stream is recycled to a second stage where the diisopropyl ether is reacted with water to produce isopropyl alcohol. The isopropyl alcohol is then recycled to the first stage. The benefit of producing isopropyl alcohol by the hydration of diisopropyl ether is that it is an easier reaction than, for example, the hydration of propylene. As a result, the process of the present invention can operate under less severe conditions, i.e., less cost.
