A two-step integrated process for the generation of diisopropyl ether from an acetone-containing stream comprises: a) reducing the acetone-containing stream over a bulk metal, nickel-rich catalyst to give an isopropanol-rich effluent; b) passing said isopropanol-rich intermediate directly to a second reactor, and c) subjecting said isopropanol-rich intermediate to dehydration conditions in the presence of hydrogen and a strong acid zeolite catalyst from the group consisting of beta -zeolite, beta -zeolite modified with one or more metals from Groups IB and VIII of the Periodic Table, and a dealuminised Y-zeolite, optionally mixed with a binder selected from Group III or IV of the Periodic Table. |
