FIELD: catalysts for organic syntheses. SUBSTANCE: catalyst is based on high-silica zeolite containing filler: Aerosil activated by alkali metal and/or ammonium fluoride. Catalyst is prepared by mixing zeolite with filler, binding agent, and activating additive followed by shaping catalyst mass into sticks or pellets which are dried and calcined. EFFECT: improved catalyst characteristics. 2 cl, 2 tbl
