PURPOSE:Lower alcohol or ether is brought into contact with a specific crystalline bismuth silicate under specified conditions to produce in high efficiency the titled mixture with no formation of durene and other compounds unsuitable for gasoline. CONSTITUTION:An alcohol and/or an ether with alkyls of 4 or less carbon atoms such as methanol or dimethyl ether is brought into contact with (B) crystalline bismuth silicate with a chemical composition of the formula (R is mono- or divalent cation; n is valency of R; M is cation of trivalent transition metal, Al3+; a+b=1; a0; b=0; y=5) to produce the objective mixture. The component B is preferably activated by heating at 400-700 deg.C in the air for 2-48hr before use. EFFECT:The process inhibits the formation of carbon and prolongs the catalyst life.
