  Provided is a method for stably and economically producing xylylenediamine with a high yield and long catalyst service life by hydrogenating dicyanobenzene that is obtained by ammoxidating xylene. By bringing an aqueous basic solution into contact with a dicyanobenzene-absorbed liquid, which is obtained by bringing an ammoxidation reaction gas into contact with an organic solvent, under specified temperature conditions, and subjecting a base and a carboxylic acid in the dicyanobenzene-absorbed liquid to a neutralization reaction so as to form an aqueous phase that contains a water-soluble salt, and then subjecting an organic phase and the aqueous phase to liquid-liquid separation so as to remove the aqueous phase, it is possible to remove the carboxylic acid contained in the dicyanobenzene-absorbed liquid with high selectivity while inhibiting loss of the dicyanobenzene. By subjecting the raw material dicyanobenzene, which is obtained by separating low boiling point compounds from the post liquid-liquid separation organic phase by distillation under reduced pressure, to hydrogenation, xylylenediamine is produced with a high yield and the service life of the hydrogenation catalyst is extended.

  提供了一种通过氢化从氨氧化二甲苯获得的二氰苯生成稳定且经济高效的二甲基二胺的方法，该方法具有高产率和长的催化剂寿命。通过将含有二氰苯的液体与水性碱性溶液接触，该液体是通过将氨氧化反应气体与有机溶剂接触获得的，在指定的温度条件下，并且使二氰苯吸收液中的碱和羧酸发生中和反应，形成含有水溶性盐的水相，然后将有机相和水相进行液-液分离以去除水相，可以高选择性地去除二氰苯吸收液中含有的羧酸，同时抑制二氰苯的损失。通过将通过减压蒸馏从液-液分离有机相中分离出低沸点化合物获得的原料二氰苯经过加氢处理，可以高产率地生产二甲基二胺，并延长加氢催化剂的使用寿命。
