“…As the mechanism and kinetics of protective layers formation determine the effectiveness of corrosion protection, this issue is important for the study of corrosion inhibitors. It was defined that physical adsorption is typical for imidazo [1,2-a]pyridinium bromides [1], and chemisorption, which is more efficient at slowing down corrosion processes, is typical for imidazo [1.2-a]azepine bromides [2], polymethyleneimidazoline bromides [3], secondary amines with triazoloazepine and substituted phenyl radicals [4][5][6][7].…”

Experimentally proved by the method of polarization resistance formation of protective layers during inhibition steel corrosion by Sulfanilamide in aqueous solutions of hydrochloric acid with different pH. It is shown the difference due to the predominance of the protonated or unprotonated form of the molecule. It was found that at predominance of protonated forms of molecules (pH £2,4) formed dense protective films and predominance of unprotonated forms of molecules (pH ³2,4) are formed layers that do not inhibit diffusion processes. Sulfanilamide provides high and stable inhibition efficiency (<90%) in acid chloride solutions in case of formation protective layers consisting of protonated molecules what to consider when use it.

Peculiarities Of Triazoloazepinium Bromides Effect On Steel Microbial Corrosion

Triazoloazepinium bromides act as biocides against sulfate-reducing bacteria and can produce an effect on mild steel microbial corrosion. It has been established that under the competing adsorption, the compounds with the properties of corrosion inhibitors can form a film, which protects the steel surface, before it is settled by corrosively active microorganisms.The protective film ensures the inhibition efficiency of up to 98.7%. With triazoloazepinium bromides of the 2nd group, corrosively active microorganisms colonize the steel surface before the inhibitor creates the protective layer. In this case, the biocorrosion accelerates by up to 6.25 times. Different effect of triazoloazepinium bromides on steel biocorrosion rate is explained by the molecular structure.
