Abstract

Pyridine and b -picoline are produced by heating ammonia with a vaporised mixture of formaldehyde and acetaldehyde in the presence of the vapour of ethanol or n-propanol. The reaction is preferably carried out at 300-600 DEG C. in the presence of a condensation catalyst. Suitable catalysts are, for example, alumina, silica or mixtures thereof which may also contain an oxide of titanium, zirconium, cerium or thorium and/or zinc, cadmium, tin, lead, tungsten, nickel, cobalt, chromium, molybdenum, iron, palladium or silver or a compound of one of these. If desired an inert diluent, such as steam or nitrogen or a hydrocarbon such as benzene may be present.
