amine carboxylate corrosion inhibitor

What is a volatile corrosion inhibitor?
Volatile corrosion inhibitors (VCIs) are substance molecules that vaporize at a significant pressure and then are adsorbed on the metal surface forming a thin corrosion protection layer. 42, 43 Most volatile corrosion inhibitors are aminocarboxylates—products of reaction between organic acids with an amine or amine derivatives.
Is polyamine a corrosion inhibitor?

How effective are amine carboxylates as vapour phase corrosion inhibitors?
Amine carboxylates as vapour phase corrosion inhibitors. Fifty three products, mostly carboxylate salts of amines, were evaluated as vapour phase corrosion inhibitors for mild steel. Fifteen compounds showed effectiveness in excess of 90%. Morpholine was the most effective amine and caprylic acid the most effective acid constituent.
How effective are amines compared to carboxylic acids?
Fifteen compounds showed effectiveness in excess of 90%. Morpholine was the most effective amine and caprylic acid the most effective acid constituent. The effectiveness of ammonium monocarboxylates decreased with increase in the length of the carbon chain of the carboxylic acid. The other carboxylates did not show such a clear trend.
