Abstract:
     The invention concerns a process for upgrading olefinic gasolines containing C5 hydrocarbons, but free of C4 hydrocarbons, by etherification. It is characterized in that the tertiary olefins of the charge are reacted with methanol; the reaction effluent being then extracted with water, in order to separate an aqueous phase containing the major part of the unreacted methanol from a hydrocarbon phase containing the major part of the formed ethers. The aqueous phase is then introduced in a distillation zone wherefrom water is separated from methanol and recycled to the extraction zone, whereas methanol is recycled to the etherification zone.
