ResumoAbstract Of many compounds examined in vapour form in moisture‐laden air, a number will, in varying degrees, confer protection upon ferrous and some non‐ferrous metals when contained in the same enclosed space. Certain esters (e.g. n ‐ and iso ‐propyl benzoates, n ‐butyl benzoates and methyl cinnamate) afford good protection to steel. Complete inhibition of the corrosion of steel and cast iron may be effected in moist air, even when heavily contaminated with sulphur dioxide, by certain amine carbonates, e.g. cyclo hexylamine carbonate. These compounds also possess, in marked degree, the property of arresting the further corrosion of iron and steel surfaces that have already become rusted by exposure to moist polluted air.
