AMMOXYDATION CATALYTIQUE DES HYDROCARBURES ET REACTIONS APPARENTEES. XXII. AMMOXYDATION DU BENZENE ET DU CYCLOHEXANE

Benzene ammoxidation at 440-550 deg C/1 at. produces, on V-Mo, Ti-Mo, Bi-Mo (oxides) catalysts, unsaturated C4 (maleo and fumaronitriles) and C6 (mucononitrile and stereoisomers) dinitriles.These initial selectivities fall with increasing conversions, and C6 dinitriles disappear above 10percent conversion by thermal or catalytic degradation.The main initial stereoisomer cis-cis (mucononitrile) is consistent with a 1-2 attack of the aromatic ring, so far unknown in catalytic oxidations.Cyclohexane ammoxidation goes through the oxidative dehydrogenation to benzene and proceduces small amounts of C4 unsaturated dinitriles along with traces of C4, C5 and C6 saturated dinitriles coming from a different reaction path.In both cases, V-Mo and Ti-Mo are the best catalysts for dinitriles production; no C6 formed on Sn-Mo, Sb-Mo and Sn-Sb-Fe-catalysts.
