| Popis: | Based on propargyl alcohol esters, new derivatives of phosphorous and 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 acid esters containing an alcohol group in their composition. For the synthesized corrosion inhibitors, an adsorption-polymerization mechanism of action is assumed, which is evidenced by the enhancement of the protective effect of these compounds with increasing temperature. |
