ABSTRACT A process for producing sec-butanol and sec-butyl tert-butyl ether from butane, characterized in that, n-butane is partially isomerized, the butanes are catalytically dehydrogenated, butadiene is selectively hydrogenated with conversion of butene-1 to butene-2, the isobutene contained in the dehydrogenation reaction mixture is etherified with recycled sec-butanol to form sec-butyl tert-butyl ether, butene-2 from the unreacted hydrocarbon mixture which contains primarily butene-2 and butane,is converted with water to sec-butanol and this is recycled to the etherification.
