Abstract
Hydrocarbon-containing materials having a low amount of unsaturation e.g., paraffinic and napththenic hydrocarbons having less than about 10 weight percent unsaturation are stabilized or made more resistant to oxidation employing a polyamines mixture obtained as a heavy by-product residue from the recovery by distillation of a polyamine obtained in the hydrogenation of branched aliphatic dinitriles. In one embodiment an isoparaffinic hydrocarbon obtained by alkylation of an isoparaffin with an olefin is rendered resistant to oxidation.
