Mobil Diisopropyl Ether Process
Published: May 1993
Mobil Research and Development Corporation recently announced the development of a process which hydrates propylene to produce diisopropyl ether (DIPE) using a zeolite catalyst. DIPE's high octane and low vapor pressure blending characteristics make it an attractive oxygenate blending candidate for reformulated gasoline as mandated by the 1990 U.S. Clean Air Act. Product quality tests show that DIPE is a suitable gasoline blending component.In this review, we evaluate the technical and economic aspects of DIPE production by direct propylene hydration.
