Abstract

PURPOSE: To prepare the titled compound useful as a raw material of polyamides, by hydrogenating dodecanedinitrile using a granular catalyst having long-lasting catalytic activity, resistant to pulverization, and containing an active component composed essentially of element iron.
CONSTITUTION: 1,12-Dodecanediamine is prepared by hydrogenating dodecanedinitrile. The hydrogenation is carried out at a relatively low temperature (but high enough to keep the sufficiently high catalytic activity), e.g. at 80W150°C, in liquid phase, under pressure (pref. 150W300kg/cm2G), in the presence of ammonia and hydrogen, and a granular catalyst having a diameter of 5W20mm and obtained by calcining or melting a mixture of iron oxide and 1W10wt%, based on the iron oxide, of aluminum oxide at≥1,400°C, cooling, crushing, and reducing in hydrogen.
EFFECT: The use of the catalyst enables the continuous operation for a long period.
