| titleOfInvention | Process for ortho- and para-alkylating diphenylamines |
| abstract | ABSTRACT OF THE DISCLOSURE Ortho-para-alkylated diphenylamines are prepared utilizing an improved, one-stage process wherein the diphenylamines are ortho-alkylated by reaction with a first olefin in the presence of an aluminum complex as the catalyst, and are subsequently para-alkylated by reaction with a second olefin using a Friedel-Crafts aluminum catalyst. The para-alkylation is carried out without prior isolation or solvent washing of the ortho-alkylated diphenylamine intermediates. |
