Study of the Corrosion Inhibition Efficiency by Using New Azo Compounds from Thiazole Derivatives

Abstract

Azo compounds were prepared by reacting thiazole derivatives with 2-naphthol, o-vanillin, 4-(dimethyl amino) pyridine, and 4-bromo aniline with thiazole derivatives. The molar conductivity of the azo compounds prepared in this study was measured using (ethanol) as a solvent and at room temperature, all compounds showed non-electrolytic behavior. The compounds were characterized by TGA/DTA, studying the thermal stability and calculating the activation energy of azo compounds, where the thermal analyses of the prepared compounds were measured to identify the temperature at which the compound disintegrates, as the compound has more than one degree of disintegration, and this variation in the degrees of disintegration and the remaining materials depends on the nature of the compound and the type of groups present in it, as well as the efficiency of their use as materials. Resistant to corrosion by weight loss method with different concentrations at constant temperature. The higher the concentration, the greater the inhibition efficiency.
