ABSTRACT:
A process is described for producing methyl tert.-butyl ether from butane-containing light hydrocarbon mixtures. The n-butane is isomerized to isobutane which is dehydrogenated to an isobutene/isobutane molar ratio of 0.4 to 2:1, the isobutene in the mixture is etherified with methanol to form methyl tert.-butyl ether and the residual isobutane is recycled for dehydrogenation. After the isomerization step, the n-butane and isobutane can be separated and the n-butane recycled. The product containing methyl tert.-butyl ether can be used as a gasoline additive.
