Abstract
A process for the production of methyl tertiary butyl ether comprising dimerizing ethylene to form a first butene-containing material; isomerizing the first butene-containing material to produce a second butene-containing material including an increased amount of isobutene relative to the first butene-containing material; and contacting at least a portion of the second butene-containing material with methanol at etherification conditions to produce an affluent enriched in methyl, tertiary butyl ether.
Claims7
A process for the production of methyl, tertiary butyl ether comprising:
- (a) dimerizing ethylene to produce a first butene-containing material which includes less than about 1% by weight butane;
- (b) isomerizing said first butene-containing material to produce a second butene-containing material including an increased amount of isobutene relative to said first butene-containing material;
- and
- (c) contacting at least a portion of said second butene-containing material with methanol at etherification conditions to produce an effluent enriched in methyl, tertiary butyl ether.
