Behenic acid (98.4 g., 0.3 mol) and triethylenetetramine (43.8 g, 0.3 mol) was reacted at 158°-161° C. until 0.3 mol of water had been evolved (25 minutes) 47.4 g (0.1 mole) of the resulting triethylenetetramine monobehenamide was dissolved in 50 ml. of perchloroethylene. To the resulting solution was added a mixture of 80.0 g (0.12 mol) of perfluorodecenyloxybenzenesulfonyl chloride and 7.0 g of sodium carbonate over a 20 minute period, while holding the temperature at 95°-120° C. After one hour at 90°-120° C., the mixture was worked up as in the preceding example to yield the product, 1.2 perfluorodecenyloxybenzenesulfonamide of triethylene tetramine monobehenamide, a tan, hard, waxy, solid with good oil, water and soil repellancy.
