Abstract:
This invention relates to a process for producing a high purity butene-1 product from n-butane via a dehydrogenation process. In one embodiment of the process the n-butane is dehydrogenated over a chromia-alumina catalyst and any butadiene formed hydrogenated to monoolefins. The monoolefins are separated and the butene-1 separated from isobutylene by reacting the isobutylene with methanol to form methyl tertiary butyl ether. The methyl tertiary butyl ether is separated from the butene-1 leaving it as a high purity product. Alternatively, the dehydrogenated product from the reactor may be contacted with a solvent to extract butadiene followed by hydrogenation, separation of monoolefins and conversion to methyl tertiary butyl ether.
