V. Vapors A. Resistance based on condensing conditions B. Dry vapors up to 100 o C are non corrosive.
Elevated temperatures can accelerate corrosion rates significantly.
B. No oxidizing contaminants. The available data for aqueous amines is sketchy. Amines have also been documented as causing SCC of copper and copper alloys, similar to that of ammonia, possibly promoted by the breakdown of the amine into ammonia. Therefore, the resistance of copper and copper alloys in amine solutions should be considered similar to that in ammonia, but less severe. Cold, dilute amine solutions may be tolerated by the copper alloys exhibiting some ammonia SCC resistance, i.e., the coppers, high copper alloys, and the copper nickels.
