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:
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.
本文描述了一种新型乙炔胺和含有该胺的水性组合物,用于抑制金属腐蚀。该组合物包含一种非氧化性酸,以及作为缓蚀剂的有效量的含乙炔不饱和叔胺,其式如下
其中 R1 和 R2 独立地为 C1-C8 烷基或苯基,R3 选自支链 C7-C10 烷基、任选与卤素、C1-C8 烷基和/或 C1-C8 烷氧基单取代或二取代的肉桂基、单取代或二取代的苯基,或者当 R1 和 R2 不是 C1-C2 烷基时,R3 可以是未取代的苯基。
