Abstract

In the processing of olefinic hydrocarbon mixtures containing isobutylene and isoamylene which are etherified with methanol to obtain higher octane components, unreacted methanol is removed from the etherified mixture by contact with a separate liquid glycol phase before unreacted hydrocarbons, substantially free of methanol, are distilled from the etherified mixture for further catalytic processing in which methanol is deleterious to the catalyst.
