摘要： A method of producing xylylenediamine by a two-stage hydrogenation of a starting phthalonitrile in a solvent. The main steps of the method are a hydrogenation step 1 and a hydrogenation step 2. In the hydrogenation step 1, a solution of the starting phthalonitrile in the solvent containing liquid ammonia is fed to an inlet of a first reaction zone and the hydrogenation is carried out in the first reaction zone in the presence of a heterogeneous catalyst, to hydrogenate nitrile groups in the starting phthalonitrile to aminomethyl groups. A part of the hydrogenation product solution from the first reaction zone is circulated to the inlet of the first reaction zone and the rest is introduced into the hydrogenation step 2 where further undergoes the hydrogenation.

摘要： Highly pure, less colored aromatic polycarboxylic acids are produced from crude aromatic polycarboxylic acids by simple procedures at low production costs. The crude aromatic polycarboxylic acid is mixed with aliphatic amine or alicyclic amine in the presence of a solvent to precipitate crystals of amine salt of aromatic polycarboxylic acid. The crystals are dissolved in water and decomposed, thereby obtaining the highly pure aromatic polycarboxylic acids.
