WATER-SOLUBLE INHIBITORS of ACID CORROSION OF STEEL

摘要

Water-soluble inhibitors of acid corrosion (the protective effect in chloride acid of 78.3 - 98.6%; in sulfate acid of 37.5-72.4%), soluble in water and aqueous solutions and the solution obtained by boiling the corresponding hydrazide in propan-2-ol and 7-methoxy-3,4,5,6-tetrahydro-2H-azepine, cooling, separating the precipitate and recrystallization from propan-2-ol, of the general formula of:,where TTMA: R = Cl; TTMA-B: R = CH3, which also has a biocidal effect of sulfate-reducing bacteria and inhibits the corrosion of steel in environments with bacterial sulfate reduction by 87.4%.
