Aliphatic hydrocarbyl-substituted aromatic amines are prepared by reacting an aromatic amine and an aliphatic hydrocarbylating agent, such as an olefin, in the presence of a heteropolyacid catalyst such as Cs2.5H0.5PW12O40, for a period of time and at a temperature sufficient to permit reaction.

Préparation d'amines aromatiques avec substitution alkylique, par réaction d'une amine aromatique et d'un agent d'alkylation, comme une oléfine, en présence d'un catalyseur de type hétéropolyacide, p. ex. Cs2.5H0.5PW12O40, pendant une période de temps et à une températures suffisantes pour permettre la réaction.
