Reaktionsschritte
A mixture of 768 g. (6 moles) 5-methyl-3-heptanone and 108 g. (1 mole) p-phenylenediamine was reacted and worked up in the same manner as that of Example 1 to give 330 g. (99%) residue of crude N,N'-bis(1-ethyl-3-methylpentyl)-p-phenylenediamine product [IVa, R2 =C2H5, R3 =CH2CH(CH3)C2H5 ] containing some mono-Schiff's base III-c and some di-Schiff's base III-d.
