4-(Pyridin-4-yl)thiazol-2-amine as an efficient non-toxic inhibitor for mild steel in hydrochloric acid solutions

Abstract

The corrosion inhibition performance and mechanism of 4-(pyridin-4-yl)thiazol-2-amine toward mild steel in hydrochloric acid were studied for the first time.

Electrochemical and thermodynamic properties of 1-phenyl-3-(phenylamino)propan-1-one with Na 2 WO 4 on N80 steel

“…The chemical structure of organic molecules, surface charge distribution and corrosive medium would have an influence on the adsorption process. The plots of C inh /θ versus C inh for PPAPO in the concentration range 1 to 10 mM at 333 K yielded a straight line with correlation coefficient value 0.9724 (figure 7), suggesting that the adsorption of PPAPO obeys the Langmuir adsorption isotherm represented by the following equation (3.6) [25,26]:…”

Experimental and theoretical research on a new corrosion inhibitor for effective oil and gas acidification

“…It can also be seen from the anodic polarization curve that DEEQ has an evident inhibitory effect on the mild steel electrode at a lower anode potential, which is related to the adsorption of DEEQ on the surface of the mild steel electrode and the formation of a protective layer of inhibitor. 10,38 However, when the polarization potential continues to increase, it can be observed that the curves are close to coinciding. This may be due to the rapid dissolution of mild steel at the strong polarization potential, which causes the desorption of DEEQ from the electrode's surface.…”

“…Therefore, adding a corrosion inhibitor is an economical and effective method that has received increasing attention. 6,7,38 According to the chemical composition, a corrosion inhibitor is divided into two parts: an inorganic portion and an organic inhibitor. The organic inhibitor molecules contain a highly electronegative polar group (O, N, S, etc.…”

Synthesis and inhibition corrosion effect of two thiazole derivatives for carbon steel in 1 ​M HCl

“…The use of thiazole derivatives as corrosion inhibitors has been discussed in several publications [37][38][39][40][41][42]. Table 4 shows the protection efficiency and ΔG ads obtained of some thiazole derivatives exploited as corrosion inhibitors of steel in a 1 M HCl medium.…”
