| titleOfInvention | DIRECT ALKYLATION OF N-ALKYL-N'-PHENYL-p-Phenylenediamine |
| abstract | 1. The method of one-step alkylation in the ring of at least one N-alkyl-N'-phenylphenylenediamine with at least one olefin, comprising heating a mixture of N-alkyl-N'-phenylphenylenediamine (diamines) and olefin (olefins) in the presence of a catalytic amount of at least at least one alkylaluminum halide at a temperature of from about 50 to about 350 ° C in a sealed vessel for from about 1 to about 30 hours! 2. The method according to claim 1, in which N-alkyl-N'-phenylphenylenediamine has the structure:! ! where R1 is selected from the group consisting of alkyl, cycloalkyl and radicals of the structural formula:! ! in which R2 may be the same or different and independently selected from the group consisting of hydrogen and methyl, R3 is selected from the group consisting of alkyl with the number of carbon atoms from 1 to 12, and n is an integer from 0 to 6.! 3. The method according to claim 2, in which R1 is selected from the group consisting of alkyls having from 1 to 50 carbon atoms, and cycloalkyls having from 3 to 30 carbon atoms. ! 4. The method according to claim 1, in which N-alkyl-N'-phenylphenylenediamine is selected from the group consisting of:! N-methyl-N'-phenyl-p-phenylenediamine; ! N-ethyl-N'-phenyl-p-phenylenediamine; ! N-propyl-N'-phenyl-p-phenylenediamine; ! N-isopropyl-N'-phenyl-p-phenylenediamine; ! N-n-butyl-N'-phenyl-p-phenylenediamine; ! N-sec-butyl-N'-phenyl-p-phenylenediamine; ! Nn-pentyl-N'-phenyl-p-phenylenediamine; ! N-1-methylbutyl-N'-phenyl-p-phenylenediamine; ! N- (1-methylheptyl) -N'-phenyl-p-phenylenediamine; ! N-1,2-dimethylpropyl-N'-phenyl-p-phenylenediamine; ! N-2-methylbutyl-N'-phenyl-p-phenylenediamine; ! N-3-methylbutyl-N'-phenyl-p-phenylenediamine; ! N-1-ethylpropyl-N'-phenyl-p-phenylenediamine; ! Nn-hexyl-N'-phenyl-p-phenylenediamine; ! N-1-methylpentyl-N'-phenyl-p-phenyl |
