Abstract

Alkyl pyridines are produced by heating a mixture of crotonaldehyde, propanol and ammonia, preferably at a temperature from 300 DEG to 500 DEG C. The process is preferably carried out in the presence of a condensation catalyst, e.g. silica, alumina or a mixture of these. In addition the catalyst may also contain an oxide of titanium, zirconium, cerium or thorium and also zinc, cadmium, tin, lead, tungsten, nickel, cobalt, chromium, molybdenum, iron, copper, palladium or silver either as the metal or a compound thereof. Some water may be present in the reaction mixture. In the example a mixture of crotonaldehyde, propanol and ammonia are heated in the presence of alumina and silica impregnated with zinc oxide to give a mixture of a -picoline, g -picoline, 2-ethyl pyridine and 3,4-lutidine.
