반응 단계
DE-A-2 429 293 discloses in Example 1 that the hydrogenation of adiponitrile in the presence of five times the weight of ammonia at from 93 to 98° C. (inlet temperature into the reactor) or at from 94 to 104° C. (outlet temperature) over an iron catalyst prepared from magnetite by reduction with hydrogen and doped with aluminum oxide, silicon dioxide, calcium oxide and vanadium pentoxide yields 98.22% of hexamethylenediamine comprising 1900 ppm of 1,2-diaminocyclohexane, and in Example 2 that the hydrogenation of adiponitrile in the presence of five times the weight of ammonia at from 93 to 98° C. (inlet temperature into the reactor) or at from 94 to 104° C. (outlet temperature) over an iron catalyst prepared from Labrador hematite ore (Fe2O3) by reduction with hydrogen and doped with aluminum oxide, silicon dioxide and calcium oxide yields 98.05% of hexamethylenediamine comprising 3500 ppm of 1,2-diaminocyclohexane.
