production method | is obtained by hydrogenation and Amination of acetone or isopropanol. 1. Acetone catalytic hydrogenation ammoniation acetone gasification after mixed with a certain amount of ammonia and hydrogen, under normal pressure and appropriate temperature, continuous catalytic reaction, catalyst for Ni-Cu-clay, reaction products by distillation, fractionation, to obtain the finished product. Raw material consumption quota: acetone 1389kg/t, liquid ammonia 376kg/t, hydrogen (99%)1023. 2. Isopropyl alcohol catalytic hydrogenation amination isopropyl alcohol, liquid ammonia, hydrogen in gas phase according to a certain proportion of mixed, in the presence of catalyst Cu-Ni-clay, synthesis of diisopropylamine crude, after extraction, separation, dehydration, the finished product was obtained by distillation. The total conversion was 86% and the yield was 96%. Containing isopropylamine 37%, diisopropylamine 33%, isopropanol 12%, water 18%, isopropylamine and diisopropylamine were isolated, and the unreacted isopropanol was recycled. The proportion of the product can be changed by adjusting the ratio of isopropyl alcohol and ammonia. The preparation method is based on acetone, ammonia and hydrogen as raw materials, in the atmospheric pressure 150~220 ℃ with nickel, copper, Clay as catalyst, acetone conversion rate of 98%, the crude monoisopropylamine and diisopropylamine were obtained, respectively, by distillation. |
