실험 절차

Patent Document 1 discloses a method of producing m-xylylenediamine from m-xylene. In the proposed method, isophthalonitrile produced by the ammoxidation of m-xylene is extracted into an organic solvent. Then, high-boiling point impurities are separated out in the first distillation step and the organic solvent is separated out in the second distillation step. Then, isophthalonitrile is taken out of the bottom of apparatus. The obtained purified isophthalonitrile is then hydrogenated after the addition of a specific solvent and liquid ammonia. This method requires increased costs for constructing production facilities because of its large number of steps. In addition, the method requires two distillation steps before the hydrogenation and further requires another distillation step for purification after the hydrogenation step. Therefore, a great quantity of energy for distillation should be consumed.
