<p>FIELD: catalysts in organic chemistry. SUBSTANCE: catalytic system contains vanadium, titanium, zirconium, and molybdenum oxides, where V<SB>2</SB>O<SB>5</SB>:TiO<SB>2</SB>:ZrO<SB>2</SB> molar ratio ranges from 1:1:2 to 1:12:25 and amount of MoO<SB>3</SB> constitutes 0.54 to 2.6 wt % of amount of V<SB>2</SB>O<SB>5</SB>. System is used in oxidative ammonolysis of alkylpyridins at 280-400 C. In this case, conversion of 3- methylpyridin, for instance, does not require water steam and ammonia is used in virtually stoichiometric or slightly excessive molar amount. EFFECT: simplified process. 6 cl, 2 tbl, 25 exr</p> |
