ABSTRACT:
The desired compounds, namely, N-phenyl-N'-alkylphenylenediamines, are prepared by the reductive alkylation of a nitrogen-containing diphenylamine and a ketone in the presence of hydrogen and a hydrogenation catalyst. The desired product may be obtained in a more economical way when effecting the process in a continuous manner by utilizing an organic solvent for the reaction which comprises an ether compound such as a monoether of a dihydric alcohol, a diether of a dihydric alcohol, or a cyclic diether.
