Indolizine quaternary ammonium salt inhibitors, part III: insights into the highly effective low-toxicity acid corrosion inhibitor – synthesis and protection performance
The accurate formulas and structures of the three compounds are characterized by high resolution mass spectrometry (HRMS) and nuclearmagneticresonance (NMR) spectroscopy. The corrosion inhibition performance of the indolizine derivatives toward N80 steel was investigated in 15 wt% HCl and 20 wt% HCl by weight loss measurements, electrochemical tests (Tafel and EIS), SEM/EDX analysis and theoretical
