ABSTRACT:
Polyamines are prepared via the batchwise hydrogenation of polynitriles by the gradual addition of the polynitrile into a fed-batch reactor which contains chromium promoted Raney.RTM. cobalt catalyst. The hydrogenation optionally is conducted in the presence of anhydrous ammonia. The polyamine product having amino groups which corresponds to the nitrile of the polynitrile is economically obtained in high selectivity and yield as the dominant product.
