Ammonia → 1,3-Benzenedimethanamine

Participants

Reaction Steps

5 g of alumina powder containing 5% by weight of ruthenium, 26.8 g of isopthalonitrile and 30 g of liquid ammonia were charged into an autoclave having a net capacity of 200 cc, provided with an electromagnetic stirrer, and subjected to reaction at a reaction temperature of 140° C. and a reaction pressure of 150 kg/cm2 for 60 minutes by continuously supplying hydrogen to the autoclave. As a result of analysis of the reaction product liquid, it was found that the yield of 1,3-BAC was 87.8% and 3-methylbenzylamine and metaxylylenediamine were obtained as by-products in yields of 4.8% and 3%, respectively, while the yield of other lower boiling and higher boiling products than the boiling point of the BAC was 4.4%.
