Abstract : Amine salts and amine adsorbed cation-exchanger have been examined to ascertain their vapour phase inhibition property for protection of metals against corrosion.The investigation has shown that amine adsorbed cation-exchangers are efficient inhibitors. They can be conveniently handled unlike free amines, are less harmful to non-ferrous metals and possess a longer life. Amine nitrites and carbonates which are well known volatile corrosion inhibitors, have shown good results. Amine benzoate's and stearates have been found to provide good inhibition under milder test conditions but failed in severe exposure conditions.
