This work is a continuation of a series of studies on the preparation of acid corrosion inhibitors derived from carboxylic acids. A synthesis was developed for acid corrosion inhibitors derived from oleic acid amides. Several syntheses were carried out in an attempt to obtain compounds with improved corrosion inhibition properties. Aminoalcohols were added to oleic acid in the first step and the resultant products were sulfated with sulfuric acid. Reactions with bases were carried out with the aim of expanding the range of such inhibitors. Salts of sulfated oleic acid amides were synthesized by reaction with aminoalcohols, sulfuric acid, and bases in aqueous solution. The protective action in dilute hydrochloric acid was evaluated in order to establish the inhibition efficiency of these compounds, some of which appear to have suitable corrosion inhibition properties. The ammonium salt of the sulfated diethanolamide of oleic acid was found to be the most efficient corrosion inhibitor among these products.

这项工作是对由羧酸衍生的酸腐蚀抑制剂的制备进行的一系列研究的延续。开发了一种由油酸酰胺衍生的酸腐蚀抑制剂的合成方法。进行了几种合成以试图获得具有改进的腐蚀抑制性能的化合物。在第一步中将氨基醇加入油酸中，所得产物用硫酸硫酸化。与碱进行反应的目的是扩大此类抑制剂的范围。通过与氨基醇、硫酸和碱在水溶液中反应合成硫酸化油酸酰胺的盐。评估在稀盐酸中的保护作用，以确定这些化合物的抑制效率，其中一些似乎具有合适的腐蚀抑制特性。油酸的硫酸化二乙醇酰胺的铵盐被发现是这些产品中最有效的腐蚀抑制剂。
