Abstract

Cyanopyridines are prepared by reacting in the gaseous phase at 300 DEG to 700 DEG C. one mole of an alkylated pyridine with 0.5 to 10 moles of oxygen, 0.5 to 1.5 moles of ammonia and 0.5 to 10 moles of steam in the presence of a solid phosphoric acid catalyst formed by heating a phosphoric acid with a solid absorbent or solid material reactive therewith until polymerization of the acid occurs together with physical, physico-chemical or chemical bonding with the solid material or absorbent, and which is further activated by incorporation of a compound of one or more of the following metals or mixtures thereof: copper, iron, cobalt, nickel, bismuth, antimony, tin, vanadium, niobium, cerium, chromium, molybdenum and tungsten. Preferred absorbent or reactive materials are carbon, silicic acid, aluminium oxide, magnesium oxide, thorium oxide, titanium oxide, zirconium oxide, boron oxide, boric acid or compounds or mixtures of these substances with each other.ALSO:An aminoxidation catalyst comprises a solid phosphoric acid formed by heating a phosphoric acid with a solid absorbent or solid material reactive therewith until polymerisation of the acid occurs together with physical, physico-chemical or chemical bonding with the solid material or absorbent, which is further activated by incorporation of a compound of one or more of the following metals or mixtures thereof: copper, iron, cobalt, nickel, bismuth, antimony, tin, vanadium, niobium, cerium, chromium, molybdenum and tungsten. Preferred absorbent or reactive materials are carbon, silicic acid, aluminium oxide, magnesium oxide, thorium oxide, titanium oxide, zirconium oxide, boron oxide, boric acid or compounds or mixtures of these substances with each other.
