Abstract

An integrated process for making propene oxide and an alkyl tert-butyl ether comprises dehydrogenating a feed stream comprising propane and iso-butane to provide a stream comprising propene, iso-butene and hydrogen; separating this stream into a stream consisting essentially of hydrogen and a stream comprising propene and iso-butene; separating the stream comprising propene and iso-butene into a stream comprising propene and a stream comprising iso-butene; reacting a part or all of the stream comprising iso-butene with an alkanol in the presence of a solid acid catalyst to provide an alkyl tert-butyl ether; and reacting a part or all of the stream comprising propene with hydrogen peroxide in the presence of an epoxidation catalyst to provide propene oxide.
