摘要：
A corrosion inhibiting aqueous composition comprises one or more aldehyde oligomers having the general formula
wherein R 1 is phenyl or substituted phenyl, R 2 and R 3 are each hydrogen, a saturated or unsaturated aliphatic group or an aryl group, R 4 is hydrogen, -(NH-CH 2 -CH 2 -) m -NH-CH 2 CH 2 NH 2 where m is from 0 to 5, or a tris(2-aminoethyl)amine group, X is oxygen or = NH, and each of the above may also be any other value which does not adversely affect the composition. The compositions are for addition to corrosive aqueous acid solutions to reduce or inhibit the corrosive effects thereof on metal surfaces.
