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

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.
