Corrosion inhibitors for water‐wetted surfaces. The compositions described are applied to water‐wetted surfaces. They are able to penetrate the water films and become adsorbed as oriented, polar, monomol. films. They contain C4–8 aliphatic mono‐hydric alcohols with a straight chain of at least 3 C per mol., a polar‐type corrosion inhibitor and an antioxidant. Butyl alcohol, amyl alcohol, 3‐methyl‐1‐butanol, 2‐methyl‐1‐butanol, 3‐pentanol and 2‐ethyl‐1‐butanol are the alcohols used. Glyceryl oleate and dioleate, Na petroleum sulphonate and cyclohexylamine laurate are the corrosion inhibitors. As antioxidants, 2, 6‐di‐tert‐butyl‐4‐methylphenol, 2, 4‐dimethyl‐6‐tert‐butylphenol, and butyl‐aminophenol are used combined with small amounts of butylphenylenediamine and di‐sec‐butyl‐p‐phenylenediamine. The compositions are useful for removal of fingerprint acids from surfaces as well as for salvage of apparatus exposed to sea water.—U.S. Pat. 2,647,839, W. A. Zisman and H. R. Baker.
