Corrosion properties of steel in 1-butyl-3-methylimidazolium hydrogen sulfate ionic liquid systems for desulfurization application

Abstract

The corrosivity of [BMIM]HSO4-based systems for desulfurization applications were investigated by weight loss and surface analyses.

Theoretical and experimental comparative study of nonlinear properties of imidazolium cation based ionic liquids

“…The bands at 1578 and 1454 cm -1 in both ionic liquids correspond to C=C and C=N stretching vibrations of the imidazole ring, respectively. The bands at 1222 and 1023 cm -1 are assigned to the S-O and S-OH stretching vibrations of HSO 4 [40].…”

Experimental and DFT studies on the ultrasonic energy-assisted extraction of the phytochemicals of Catharanthus roseus as green corrosion inhibitors for mild steel in NaCl medium

“…Hence, the stretching frequency at 1000 cm À1 is related to the vibrations of C-O bond on the mild steel surface. [49][50][51] The spectroscopy studies conrmed the chemisorbed phytochemicals on the mild surface. As shown in XRD of Fig.…”

Tribological Properties of Ionic Liquids

“…[29] The corrosion products are containing mainly metal fluorine and metal oxide on the surface which are experimentally verified. [30] After detailed investigation, halogenated ILs have hazardous and toxic effects to the environment and corrosive nature towards the engineering surfaces. The halogenated ILs can produce toxic and corrosive products after decomposition under different tribo-chemical reaction conditions for environment and the surface-engineering.…”
