A process for alkylation of a N′-phenyl-N-alkyl-p-phenylenediamine of specified formula in an ionic liquid unexpectedly produces a N′-phenyl-N-alkyl(alkylphenylene)diamine of a second specified formula. The use of an inorganic liquid permits convenient separation of the alkylated reaction product from the reaction mixture.
在一种离子液体中,通过烷基化特定化学式的N'-苯基-N-烷基-p-苯二胺的方法,意外地产生了第二个特定化学式的N'-苯基-N-烷基(烷基苯基)二胺。使用无机液体可以方便地将烷基化反应产物与反应混合物分离。
