Abstract: Allylamine was prepared from the ammonolysis of allyl chloride or the reaction of allyl chloride with hexamethylenetetramine in ethanol. The selectivity of allylamine was improved from 21.4% to 67.6% when the reaction was carried out in ethanol instead of liquid ammonia. At the same time, the selectivity of allylamine was increased from 13.3% to 67.6% when the molar ratio of NH3 to allyl chloride was increased from 4.5∶1 to 25∶1.However, the reaction of allyl chloride and hexamethylenetetramine in ethanol produced allylamine with high selectivity (100%) and high yield (87%).The synthesis of allylamine from the reaction of allyl chloride and hexamethylenetetramine in ethanol was more straightforward and convenient.
