摘要：Process for producing and isolating methyl-tert-butyl ether (MTBE) comprisingetherifying isobutene, contained in a C.sub.4 hydrocarbons mixture, with methanol in thepresence of a recycle stream of C.sub.5 and/or C.sub. 6 hydrocarbons, separating fromthe obtained reaction product, by fractionation, at least the major part of theunconverted C. sub.4 hydrocarbons, and discharging them, and fractionating the

remaining product in two fractions, one of which contains an azeotrope of methanol withthe C.sub.5 and/or C.sub. 6 hydrocarbons and is recycled, the other fraction containingthe purified MTBE.
