FIELD: petrochemical processes and catalysts.
SUBSTANCE: invention relates to supported olefin metathesis catalyst and to a olefin metathesis process using the latter. Catalyst is essentially composed of transition metal or oxide thereof, or a mixture of such metals, or oxides thereof deposited on high-purity silicon dioxide containing less than: 150 ppm magnesium, 900 ppm calcium, 900 ppm sodium, 200 ppm aluminum, and 40 ppm iron. When pure 1-butene comes into interaction with this catalyst under metathesis reaction conditions, reaction proceeds with 2-hexene formation selectivity at least 55 wt %. Use of catalyst according to invention in olefin metathesis process minimizes double bond isomerization reactions.
EFFECT: increased olefin metathesis selectivity regarding specific products.
