Quaternary pyridinium salts as inhibitors of mild steel biocorrosion

Abstract

A number of new quaternary pyridinium salts with amide fragment and aryl substituents have been obtained, demonstrating the inhibition efficiency of 50.0- 97.2 % under the biocorrosion of mild steel, induced with sulfate-reducing bacteria of Desulfovibrio and Desulfomicrobium genera. It has been established that inhibition efficiency of the studied quaternary salts is caused by their effect on microbiological factor.
