Inclusion of a branched alcohol in the catalytic hydrogenation reaction involving an aliphatic nitro compound dramatically increases the efficiency of the conversion of nitro groups into amino groups. This discovery is of particular value in the production of polyalkyleneamines via nitration of a polyalkene, such as a polybutene, and its subsequent reduction. The polyalkyleneamines so produced are useful as dispersant additives for motor oils and fuels.
