| titleOfInvention | Alkylation of an aromatic amine,in particular diphenylamine, with polyisobutylene oligomers |
| abstract | A process for the preparation of an alkylated aromatic amine, liquidnat room temperature and atmospheric pressure, preferably alkylatedndiphenylamine, which comprises alkylating the aromatic amine with anpolyisobutylene in the presence of a suitable alkylation catalyst,npreferably a clay catalyst, wherein the polyisobutylene has an averagenmolecular weight in the range of 120 to 600, contains at least 25%nmethylvinylidene isomer and wherein the mole ratio of saidnpolyisobutylene to said aromatic amine is in the range of 1.0:1.0 ton4.0:1.0. |
