Filed:

Oct 7, 1998
Appl. No.:

9/167329

International Classification:

C07D30106
US Classification:

549533
Abstract:

An integrated process is provided for the production of propylene oxide from propane wherein propane is dehydrogenated to propylene and hydrogen and the resulting propylene, propane, and hydrogen mixture together with added oxygen is reacted over a palladium on titanium silicilite catalyst to form propylene oxide, the molar ratio of oxygen to hydrogen in the reaction feed being at least about 2/1.
