ABSTRACT:
Mixtures of N,N'-disubstituted paraphenylenediamines are produced in a process wherein a nitrogen-containing compound such as 4-nitrodiphenylamine is reductively alkylated with a plurality of ketones in sequence. Preferably, one ketone is reacted to completion with an excess of the nitrogen-containing compound, then an excess of a second ketone is added and the reaction is continued until the nitrogen-containing compound is consumed. The product is then separated from the volatiles and the unreacted portion of the second ketone is recovered.
