A quinoline-based quaternary ammonium salt dimer as corrosion inhibitor for N80 steel in lactic acid solution

Upgrading of the biomass-derived platform compound 5-hydroxymethylfurfural to high-value chemicals: an environment-friendly corrosion inhibitor

“…The inhibition efficiencies of 1b at 120 ppm reach 97.2%, indicating that it is an effective corrosion inhibitor for mild steel in HCl medium. In addition, we compared the EIS inhibition efficiencies of some typical biobased corrosion inhibitors [42][43][44] and quaternary ammonium salt type corrosion inhibitors [45][46][47] reported in the past three years with that of the inhibitor developed in this work. As depicted in Table 3, only a very low concentration (only 120 ppm) of inhibitor 1b is required to give high efficiency.…”
