Filming amines are fed continuously into boiler feedwater to protect metal surfaces from corrosion caused by dissolved oxygen and carbon dioxide in condensate water.  The amine forms a thin film on the surfaces that repels the potentially corrosive water.


The Methyl Orange Method


Reference: ASTM D 2327-80, Mono- and Dioctadecylamines in Water.


CHEMetrics 3-minute procedure uses the standard methyl orange chemistry and features a unique extraction technique. The extraction eliminates several steps required in other procedures and provides increased sensitivity.


The filming amine compound reacts with methyl orange to form a yellow-colored complex that is extracted into an immiscible organic solvent. Results are expressed in ppm (mg/L) octadecylamine.
