Abstract
a. L'invention concerne un procédé de préparation de 2-méthylpyridine et de 3-méthylpyridine par réaction catalytique d'acroléine et d'acétone en phase gazeuse. b. On utilise comme catalyseurs, dans un lit fluidisé, des silicates d'aluminium contenant de 3 à 30 % d'oxyde d'aluminium, où la surface BET est de 200 à 800 m**2/g, le volume des pores de 0,4 à 1 cm**3/g et le diamètre des pores de 20 à 100.10** -8 cm. c. Le procédé donne des rendements beaucoup plus élevés que les procédés connus, et le rendement espace/temps est aussi très favorable.
