CASE 1293 A B S T R A C T O F T H E D I S C L O S U R E An improved process is disclosed for producing gasoline-grade C2-C4 alcohols from aqueous mixtures which contai.n said alcohols: the improvement consists in that the aqueous mixture is reacted with a tertiary olefin in the presence of a catalyst having an acidic character, at a temperature of from 40°C and. 90°C and at a space velocity comprised between 5 and 25 litres of reactants per litre of catalyst in an hour. Preferred catalysts are the acidic ion-exchange resins and especially those having -SO3H groups Temperature and space velocity ranges are critical in order to minimize the parasitic ester-forming reactions.-
