Abstract
A hydrocarbon conversion process which net high purity isobutane feed streams into two product streams containing an ether such as methyl tertiary butyl ether (MTBE) by reaction with methanol or ethanol. The isobutylene, alcohol and a recycle stream containing C.sub.4 hydrocarbons, alcohol and the product ether are passed through an etherification zone. The total etherification zone effluent stream is separated in a single fractionation column. Preferably the new overhead of the fractionation column is divided into the recycle stream and a second portion which is combined with a portion of the bottoms of this column to produce a gasoline grade MTBE product stream. The remainder of the fractionation column bottoms is a second product stream of chemical grade MTBE.
