Abstract

Alkyl pyridines are prepared by heating together a mixture of methyl vinyl ketone, acetaldehyde and ammonia. The process is preferably carried out in the presence of a condensation catalyst and the preferred catalyst is silica and/or alumina which may contain titania, zirconia, ceria or thoria and also zinc, cadmium, tin, lead, tungsten, nickel, cobalt, chromium, molybdenum, iron, copper, palladium or silver or a compound thereof. Among the products are, for example, a -picoline and g -picoline.
