ABSTRACT:
This invention relates to a process for the preparation of an iron catalyst used for the hydrogenation of organic compounds comprising partially oxidizing iron or an iron alloy in particulate form at an elevated temperature in the presence of gaseous oxygen until a weight gain of from 5% to 32% is obtained; and then reducing the partially oxidized iron or iron alloy at an elevated temperature in a stream of hydrogen.
The invention also relates to a process for the preparation of primary amines comprising catalytically hydrogenating nitriles corresponding to said primary amines in the presence of an iron catalyst of the invention.
