Experimental Studies of Catalytic Hydrogenation of Isophthalonitrile for Meta-Xylenediamine Preparation

Article Preview

Abstract:

With Raney nickel catalyst, the process of catalytic hydrogenation of isophthalonitrile for meta-xylenediamine preparation using aniline as the solvent is studied in this paper. The effect of the amount of catalyst, the reaction pressure and temperature is discussed. The results show that: on the conditions of the initial raw materials concentration for 2.0mol/L, the ratio of the catalyst quality and the IPN quality for 1/10, the reaction temperature for 100°C, the reaction pressure for 35bar, the reaction inhibitor NaOH for 0.6g and some additives, the reaction is conducted for 80min and the quality yield of meta-xylenediamine is up to 98.58%.
