We study the properties of the quaternary salts of pyridinium, imidazopyridinium and imidazoazepinium as inhibitors of the corrosion of St3ps steel caused by sulfate-reducing bacteria of the Desulfovibrio genus. These bacteria can be regarded as the main component of the corrosive natural communities of soil. It is shown that the role of criterion of the efficiency of quaternary salts in the case...
We have investigated the inhibiting action of acetonitrile derivatives and secondary amine in a hydrochloric acid medium during corrosion of low-carbon steel. It is shown that the protective effect ranges from 86.5 to 92.5% (2 mmole/liter) in a 1 M solution of hydrochloric acid, from 51.2 to 89.6% in a hydrogen sulfide medium, and from 14.5 to 87.3% (3.5 mmole/liter) under biocorrosion. Comparing...
