摘要：

Fifty three products, mostly carboxylate salts of amines, were evaluated as vapour phase corrosion inhibitors for mild steel steel. 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.
