Anti-corrosion properties of new imidazolium-based ionic liquids as a function of cation structure

Effect of Alkyl Chain Length on the Corrosion Inhibition Performance of Imidazolium-Based Ionic Liquids for Carbon Steel in 1 M HCl Solution: Experimental Evaluation and Theoretical Analysis

“…12,13 Related studies have demonstrated that the corrosion inhibition performance of imidazolium-based ionic liquid inhibitors is greatly influenced by the composition of anions and cations and the number of substituent groups. 14,15 Additionally, the chain length of alkyl substituent groups also plays a crucial role in determining the inhibition efficiency of not only imidazolium-based ionic liquids but also other corrosion inhibitors. Cao et al 16 researched the inhibition effects of two kinds of 1-(4-sulfonic acid) butyl-3alkylimidazolium hydrogen sulfate with the alkyl chain length of ethyl and decyl on carbon steel in 0.5 mol L −1 HCl.…”

Alkyl phosphonium‐based ionic liquids as promising additives for the corrosion protection of epoxy coatings in saline medium: Effect of the anion

“…The use of organic inhibitors constitutes another fruitful strategy for controlling, reducing, or even preventing reaction between the substrate and the aggressive components 18 . In this regard, ionic liquids (ILs) appeared as promising corrosion inhibitors for a series of metallic substrates due to their low melting point, high ionic conductivity, and low vapor pressure 18–26 . ILs were also combined with some particles to improve anticorrosion efficiency to epoxy coatings.…”

“…18 In this regard, ionic liquids (ILs) appeared as promising corrosion inhibitors for a series of metallic substrates due to their low melting point, high ionic conductivity, and low vapor pressure. [18][19][20][21][22][23][24][25][26] ILs were also combined with some particles to improve anticorrosion efficiency to epoxy coatings. In fact, epoxy coatings loaded with reduced graphene oxide (RGO), 27 GO, 15,28,29 PAni, 9 and PAni/carbon nanotube hybrid materials 8,9 modified with imidazolium-based ILs presented better anticorrosion efficiency when compared with the systems without IL.…”

Experimental and Theoretical Studies of the Corrosion Inhibition Performance of Fatty Acid-based Ionic Liquids for Mild Steel in 1 M HCl: Effects of the Varied Alkyl Chain Length in the Anionic Group

“…In recent years, ILs as efficient corrosion inhibitors have attracted great attention due to their environment friendliness. To inhibit the corrosion reaction, the functional cations of ILs could produce a protective adsorption film through electrostatic interaction or coordinate bond between a lone electron pair and an Fe atom. − Many researchers have investigated the impacts of the nature and the alkyl chain in the cations on their inhibitory property. − El-Hajjaji et al investigated the corrosion inhibition performance of 1-(3-phenoxypropyl) pyridazin-1-ium bromide for mild steel in 1 M HCl, which could reach the maximum inhibition efficiency of 91.09% at 1 mM at 298.15 K . Azeez et al found that lengthening the cationic alkyl chain length can promote the protective property of the three ILs .…”
