Dual active ionic liquids and organic salts for inhibition of microbially influenced corrosion

Abstract

We describe a series of novel compounds designed to combat the bacterial growth that leads to microbially induced corrosion on steel in the marine environment. A synergistic effect of the ionic components in these dual active organic salts is demonstrated.

New atranes and similar ionic complexes. Synthesis, structure, properties

“…It is known that biological activity of similar compounds can be significantly enhanced if essential metals are incorporated in their skeletons . In this vein, HMA and their congeners represent very promising compounds (Figure b and Figure ).…”

“…In 2012, similar compounds (ionic liquids or salts of tertiary amines and some acids) were called “dual active” …”

Anti-bacterial and anti-corrosion effects of the ionic liquid 1-butyl-1-methylpyrrolidinium trifluoromethylsulfonate

“…Therefore, a broad range of ionic liquids with anti-microbial activity can be used as biocides. Forsyth et al [22,23] synthesized and evaluated a number of novel ionic liquids as antimicrobial agents to combat biofilm formation and microbially influenced corrosion of steel in the marine environment. Seddon et al [11] showed the antibiofilm activities of a series of 1-alkyl-3methylimidazolium chloride ionic liquids, and the activity intensifies as the alkyl chain length increases.…”

The effect of treatment time on the ionic liquid surface film formation: Promising surface coating for Mg alloy AZ31

“…[15] In addition, ILs have been highlighted for their potential use as pharmaceuticals [16] and antimicrobials. [17] On the other hand, it has been suggested that ILs with at least one long hydrogen lipophilic substituent on the cation, (making the ILs relatively hydrophobic), can disrupt the membrane of bacterial cells, and cause the death of the cells. [17] Inspired by these prior works, it would appear that control over the corrosion performance coupled with surface biocompatibility of an Mg alloy implant may be achieved through control of IL chemistry and IL treatment processes.…”
