Abstract: The gaseous mixture resulting from the catalytic reaction of 3-methylpyridine with ammonia and oxygen is treated with water to recover 3-cyanopyridine. The treatment takes place in two steps. In the first step there is used a temperature of about 30 DEG to 60 DEG C. and in the second step at a temperature about 10 DEG to 30 DEG C. lower than in the first step.

Abstract: Crude nicotinamide is purified by a recrystallization and thereby is particularly freed from nicotinic acid and salts of nicotinic acid. As solvent there is used 2-methylpropanol-1 containing water. The warm solution after dissolving the crude nicotinamide is treated with ion exchangers. In this process an outstandingly pure nicotinamide is obtained with favorable yield with only a single recrystallization.

Abstract: The present invention provides a process for producing pyridines which are aromatically or heteroaromatically substituted in the 2 and 6 positions, in which aromatically or heteroaromatically substituted ketones having at least one reactive methylene group adjacent to the keto group, are reacted at temperatures from approximately 250 to 500.degree.C with aliphatic aldehydes in the gas phase in the presence of ammonia and in the presence of a catalyst having dehydrating and dehydrogenating properties.

Abstract: The present invention relates to a process for the production of pyridine and 3-methyl pyridine by catalytically reacting acrolein and acetaldehyde with ammonia in the gas phase, wherein the catalysts used are highly disperse aluminium silicates which contain from 3 to 30% by weight of aluminium oxide and which have a BET-surface of from 200 to 800 m2/g, a pore volume of from 0.4 to 1.0 cm3/g and a pore diameter of from 20 to 100.10-8 cm.
