Abstract (en)
A novel acetylenic amine and an aqueous composition containing said amine for inhibiting the corrosion of metals is described. The composition comprises a non-oxidizing acid, and, as a corrosion inhibitor, an effective amount of tertiary amine containing acetylenic unsaturation having the formula: <CHEM> wherein R1 and R2 are independently C1-C8 alkyl or phenyl and R3 is selected from the group of branched chain C7-C10 alkyl, cinnamyl optionally mono- or di-substituted with halo, C1-C8 alkyl and/or C1-C8 alkoxy; mono- or di-similarly substituted phenyl or, when R1 and R2 are other than C1-C2 alkyl, then R3 can be unsubstituted phenyl.
