Synthesis of 2,3-Dihydroxypropylsulfanyl Derivative Nonionic Surfactants and Their Inhibition Activities Against Metal Corrosion in Acidic Media

Metallic corrosion is one of the most important problem in various industrial fields. One of the most effective methods to deal with metallic corrosion is to design and use appropriate organic corrosion inhibitors. In the present study, various amide-based, sulfur-containing nonionic surfactants were synthesized and characterized by spectroscopic methods. The corrosion inhibition properties of these synthesized compounds were investigated. For this purpose, mild steel coupons were immersed for 24 hours at room temperature in 1 M HCl containing different concentrations of inhibitor according to the ASTM NACE / ASTMG31-12a standart method. As a result of these corrosion tests, the synthesized compounds exhibited very good inhibitory properties (76.58-93.74 IE%). Surface characterization studies were also performed for the metal coupons to support the obtained corrosion inhibition efficiency results.
