| titleOfInvention | Liquid alkylated diphenylamine antioxidant |
| abstract | Alkylating diphenylamine to obtain reaction products involves reacting unsubstituted diphenylamine with diisobutylene in the presence of a clay catalyst at 105 - 200 [deg] C and forming a mixture of diphenylamine and alkylated diphenylamine. Alkylating diphenylamine to obtain reaction products involves reacting unsubstituted diphenylamine with diisobutylene in the presence of a clay catalyst at 105 - 200 (preferably 105 - 157, especially 110 - 150, particularly 160 - 200) [deg] C for less than 5 hours where the unsubstituted diphenylamine contains polysubstituted diphenylamine (less than 20 wt.%) and the diisobutylene:unsubstituted diphenylamine mole ratio is 1:0.5 - 1:1.6 (preferably 1:0.7 - 1:1.6) or 0.6 - 1.2; and forming a mixture of diphenylamine and alkylated diphenylamine containing (wt.%) dioctyldiphenylamine (less than 25 or 5 - 25, preferably 10 - 20), monooctyldiphenylamine (at least 50, preferably at least 60) or (50 - 75, preferably 55 - 75) and unsubstituted diphenylamine (less than 25, preferably less than 20) or (10 - 25, preferably 12 - 20). Provided that the total amount of unsubstituted diphenylamine and diooctyldiphenylamine is less than 45 wt.%. |
