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.
在涉及脂肪族硝基化合物的催化氢化反应中加入支链醇,可显著提高硝基转化为氨基的效率。这一发现对于通过聚烯(如聚丁烯)的硝化及其随后的还原反应生产聚亚烷基胺具有特别重要的价值。生产出的聚亚烷基胺可用作机油和燃料的分散剂添加剂。
