Abstract
Disclosed is a method of reducing the corrosion of a carbon steel reboiler in which a reboiler fluid containing nitrogen trichloride is heated to decompose the nitrogen trichloride. About 1 to about 100 ppm, based on the reboiler fluid weight, of a source of iodine, is added to the reboiler.
