Abstract
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.
