Mixed hydrocarbons of predominantly four carbon atoms each are subjected to etherification with methanol, to make ether from the tertiary olefin in the mixture; the unreacted hydrocarbons, after separation from the ether by distillation, are contaminated with methanol which is removed by absorption or extraction with a glycol before the hydrocarbons are subjected to further processing in which the methanol is detrimental.

Method for processing etherified light hydrocarbon mixtures to remove

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.

Etherification processing of light hydrocarbons

A process for preparing, from tertiary olefin containing hydrocarbon fractions, a hydrocarbon fraction containing tertiaryamyl methyl ether, the process achieving high conversion of 2-methyl butenes to the ether by etherification with methanol after adequate separation of the 2-methyl butenes from other tertiary olefins, the improved conversion being achieved by separating unreacted 2-methyl butenes from etherified material and recycling them for further reaction.
