This paper descrlbcs the mvestlgatlons carned out on the kinetics of the vapour-phase ammoxldatlon of 3-methyl-pyrldme to 3-cyanopyrldme. over a Cr109 promoted Vz05-A1203 catalyst The reactlon was carried out m a packed bed flow reactor at atmospheric pressure and In the temperature range 30&37O"C T
V,05/A1203 catalysts of different vanadium contents were prepared by contacting powdered y-A&O, with aqueous solutions of different concentrations of NH4V03. Calcined catalysts with vanadium loadings below the monolayer coverage of A1203 possessed adsorbed V-oxide layer which resisted dissolution in
