An aminoalkyl imidazolines of the formula:;;having p-octyloxy-, p-dodecyloxy-, or p-octadecyloxy-phenyl pendants as hydrophobes, for use to mitigate mild steel corrosion. An electron-rich aromatic ring, in conjugation with an amidine motif, imparts increasing corrosion inhibition efficiencies with an increasing hydrophobe chain length. X-ray photoelectron spectroscopy confirms the formation of an aminoalkyl imidazoline film on a metal surface prior to reaching a critical molar concentration. |
