N-alkylated arylamines are prepared by reaction of arylamines which have at least one hydrogen atom on the nitrogen, with olefins or cycloolefins which can have substituents which are inert under the reaction conditions, at temperatures from 180 DEG to 450 DEG C, in the presence of catalysts.

Beschreibung
Zusammenfassung:	N-alkylated arylamines are prepared by reaction of arylamines which have at least one hydrogen atom on the nitrogen, with olefins or cycloolefins which can have substituents which are inert under the reaction conditions, at temperatures from 180 DEG to 450 DEG C, in the presence of catalysts. The improvement is that silicic acid which contains from 0.1 to 30 percent by weight of phosphoric acids, based on silicic acid, is used as the catalysts and that catalytic amounts of water are employed. N-alkylated arylamines are starting materials for the manufacture of dyes, pesticides, plant protection agents and growth regulators, and can also be used as mineral oil additives.
