Abstract: The reaction of allyl alc. (I) with gaseous NH3 (II) at higher temps. by applying a catalyst of an oxide-carrier, salt, and metal-carrier type was studied. The relation of yield of pyridine bases on incoming speed of I, the mol. ratio of I and II, reaction temp., the type and aging of catalyst was detd. At 310° with the incoming speed of I 20.5 g. per hr. on 50 g. Pd-Al2O3 catalyst in an iron tube, 36.19% basic portion (III) was produced. III was composed of 59.70% β-picoline, 15.80% 3,5-dimethylpyridine, 7.32% 3,5-dimethyl-4-ethylpyridine and 17.10% undistd. residue. The best results were obtained in a copper tube with the incoming speed of I 20.5 g. per hr. on 30 g. Pd-Al2O3 catalyst with a 1:3 molar ratio of I to II.
