Abstract

3-Ethyl-4-methyl pyridine and 2-n-propyl pyridine are prepared by reacting together in the vapour phase and at an elevated temperature a mixture of crotonaldehyde, n-butyraldehyde and ammonia. A condensation catalyst, e.g. alumina, silica or alumina and silica admixed with titania, zirconia, ceria or thoria and which may contain zinc, cadmium, tin, lead, tungsten, nickel, cobalt chromium, molybdenum, iron, copper, palladium or silver may be present. The reaction takes place at 300-500 DEG C., and the ammonia (vapour) may be added to the aldehyde mixture. In an example lead fluoride is used as the catalyst and a - and g -picotine and pyridine are formed in addition to the compounds above.
