phosphonic acids of the acetylene series of various structures were synthesized (10 compounds). The prepared substances (6 compounds) significantly inhibit the corrosion of 08kp low-carbon steel in 5 M HCl (T = 20–60°C). The protective effect of these inhibitors increases with a rise in their content in solution and with increasing temperature. The strongest inhibition of steel corrosion is provided by phosphonic
摘要 基于炔丙醇酯,合成了各种结构的乙炔系列的亚磷酸和膦酸的新衍生物(10种化合物)。所制备的物质(6种化合物)可显着抑制08kp低碳钢在5 M HCl中(T = 20–60°C)的腐蚀。这些抑制剂的保护作用随着溶液中含量的增加和温度的升高而增加。通过在其组成中包含醇基的膦酸酯提供对钢腐蚀的最强抑制作用。对于合成的缓蚀剂,假定了吸附-聚合的作用机理,这通过这些化合物随温度升高的保护作用增强而得到证明。
