An alkylated 1,3-benzenediamine compound used as a deposit-control lubricant additives for organic materials including lubricating oil, gasoline, and diesel fuels. The invention improves the oxidative stability of the lubricants and fuels by adding the alkylated 1,3- benzenediamine compound. The alkylated 1,3-benzenediamine compound is formed using a catalytic hydrogenation that alkylates the 4 and/or 6 position of the central aromatic ring.
