Abstract: PROBLEM TO BE SOLVED: To remove a halogenized substance from a nitrile mixture for enabling the production of an amine from the nitrile mixture afterwards by heat/treating the nitrile mixture containing the halogenized substance, adding a base to the heat-treated nitrile mixture and removing the base from the neutral mixture. SOLUTION: This method for removing a halogenized material presenting as a form of a phase transition catalyst from a nitrile mixture, is to perform a heat-treatment the nitride mixture containing the halogenized substance at 50-350 deg.C. The heat treatment is performed by setting the pressure and temperature for distilling the nitrile in the mixture at 50 m bar pressure, and 227-230 deg.C bottom temperature and 163 deg.C top temperature. Then, after adding 5-50 wt.% concentration of a base such as NaO into the nitrile mixture while agitating, the halogenized substance is removed from the nitrile mixture. And then, by hydrogenating the obtained nitrile in the presence of a catalyst such as Ni and Co at 60-160 deg.C, especially preferably 90130 deg.C to form an amine.
