Abstract
Process for the preparation of dialkylpyridines, optionally together with aminopropanols, characterized in that a 1,1,1-trimethylol alkane or alkene of the general formula: ** (see formula) ** Wherein r represents an optionally substituted linear or branched alkyl or alkenyl radical, it is reacted with at least half of the equimolar amount of ammonia and/or an amine, at a temperature of 180º to 600º c, optionally in the presence of a polar solvent and an acid catalyst and optionally under pressure.
