Abstract
Process for producing and isolating methyl-tert-butyl ether (MTBE) comprising etherifying isobutene, contained in a C.sub.4 hydrocarbons mixture, with methanol in the presence of a recycle stream of C.sub.5 and/or C.sub.6 hydrocarbons, separating from the obtained reaction product, by fractionation, at least the major part of the unconverted C.sub.4 hydrocarbons, and discharging them, and fractionating the remaining product in two fractions, one of which contains an azeotrope of methanol with the C.sub.5 and/or C.sub.6 hydrocarbons and is recycled, the other fraction containing the purified MTBE.
