It is made from acetone or isopropyl alcohol through hydrogenation.
Ammoniation method 1. Acetone catalytic hydrogenation of acetone mixed with a certain amount of ammonia, hydrogen, after gasification under atmospheric pressure and the appropriate temperature, continuous catalytic reaction, catalyst for the Ni - Cu - clay, reaction product after distillation, fractionation, the finished product.
Raw material consumption quota: acetone 1389kg/t, liquid ammonia 376kg/t, hydrogen (99%) 1023m3.
Ammoniation method 2. Isopropyl alcohol catalytic hydrogenation isopropyl alcohol, liquid ammonia, hydrogen in the gas phase in a certain proportion of mixture, in the presence of Cu - Ni - clay catalyst, synthesis of diisopropylamine crude products, through the extraction, separation, dehydration, distillation to finished products.
The total conversion rate is 86%, and the product yield is 96%.
It contains 37% of isopropyl amine, 33% of isopropyl amine, 12% of isopropyl alcohol, 18% of water, diisopropylamine and diisopropylamine, and the non-reactive isopropyl alcohol cycle is used.
Adjust the ratio of isopropanol to ammonia, which can change the proportion of products.
