    • Corrosion inhibition of metals is obtained treating a system with a corrosion-inhibiting amount, preferably 1 to 10000 ppm, of an optionally-substituted .beta.-pyridyl-ethylamine or a salt thereof, which may be prepared by reacting an amine with a vinylpyridine, preferably in the presence of an acidic catalyst such as acetic acid. The .beta.-pyridyl-ethylamine is a compound of the general formula: ##STR1## wherein R is an alkyl, aryl, aralkyl, alkaryl, halo or amino group of a group --COX where X is hydrogen, alkyl, aryl, hydroxy, alkoxy, aryloxy, amino or halo group, n is zero or an integer from 1 to 4, and R.sup.1 and R.sup.2, which may be the same or different, each represent a hydrogen atom, an optionally substituted hydrocarbyl radical, an alkylamino radical, a heterocyclic radical or a group ##STR2## or R.sup.1 and R.sup.2 with the intervening nitrogen atom together represent a saturated or unsaturated heterocyclic ring optionally containing one or more additional heteroatoms.
    • 获得金属的腐蚀抑制,其处理具有腐蚀抑制量,优选1至10000ppm的任选取代的β-吡啶基 - 乙胺或其盐的体系,其可通过使胺与乙烯基吡啶反应制备,优选 在酸性催化剂如乙酸的存在下进行。 β-吡啶基 - 乙胺是通式如下的化合物:其中R是基团-COX的烷基,芳基,芳烷基,烷芳基,卤素或氨基,其中X是氢,烷基,芳基,羟基,烷氧基 ,芳氧基,氨基或卤代基,n为0或1至4的整数,并且可以相同或不同的R 1和R 2各自表示氢原子,任选取代的烃基,烷基氨基,杂环 基团或基团,或具有插入氮原子的R 1和R 2一起表示任选含有一个或多个另外的杂原子的饱和或不饱和杂环。
