Green Brönsted acid ionic liquids as novel corrosion inhibitors for carbon steel in acidic medium

Abstract New ionic liquids with multiple Brönsted acid sites were synthesized in ≥98% yield, and their inhibiting properties for the corrosion of carbon steel in 0.5 M HCl solution had been evaluated using electrochemical impedance spectroscopy, potentiodynamic polarization and weight loss method, f...
