Abstract
Conjugated diolefines are prepared by reacting a mono-olefin containing not less than 4 carbon atoms in the vapour phase with molecular oxygen over an oxide composition containing antimony and iron as oxidation catalyst. The oxide composition may be a mixture of the metal oxides or a compound containing both metals, i.e. iron antimonate. The compositions are prepared (1) by mixing the metal oxides or compounds, e.g. hydroxides, nitrates and basic nitrate which on heating give the oxides, (2) by mixing antimony and iron salts, neutralizing the mixture with ammonia and recovering the precipitate. Catalyst activity is increased by preheating the oxide composition to 500 DEG to 1100 DEG C. and the oxide composition may be on a support, e.g. silica. Mono-olefine used are butene-1, butene-2, 3-methylbutene-1 and 2-methylbutene-2 and these may be present in amounts of 1% to 25% by volume of the feed gas which may also contain 1 to 21% by volume of oxygen and a diluent, e.g. nitrogen or steam. The reaction takes place at below 550 DEG C. with a contact time of 1 to 30 seconds. Sub, normal and superatmospheric pressure are used and fixed and fluid bed reactors are employed. The products, e.g. butadiene or isoprene may be recovered by solvent extraction or condensation followed by fractionation. Specification 902,952 is referred to.
