| Abstract: | A dendritic oligomeric quaternary ammonium salt surfactant was synthesized in absolute ethanol solvent via ring-opening reaction and quaternization reaction of starting materials(ethylenediamine,epichlorohydrin and dodecyl dimethyl amine).Performance of resultant oligomeric surfactant for N80 steel in 20% HCl solution was investigated based on weight-loss test and measurement of polarization curve and electrochemical impedance spectra.Results show that as-synthesized oligomeric surfactant has good corrosion... |
