ABSTRACT:
A method of inhibiting corrosion of metals comprising applying to a metal surface in an effective concentration a saturated aliphatic triamine of 9 carbon atoms having at each terminal position a primary amino group and being branched in the 4-position of the main chain. Such specific triamines include 1,3,6-triaminomethylhexane and 1,2,3-triaminoethylpropane. Addition products and condensation products derived from these organic triamines are also effective. The present anti-corrosive agents show a remarkable rust preventive effect to metals even when used in a small amount and are non toxic.
