  • Corrosion inhibition with alkoxy aromatic imidazolines
    Patent number: 9868894
    Abstract: 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.
    Type: Grant

  • Polymerization of bis[3-(diethoxyphosphoryl)propyl]diallylammonium chloride
    Patent number: 9120094
    Abstract: A symmetrically substituted cationic monomer and its corresponding cationic polyelectrolyte (CPE) (+) bearing two identical (diethoxyphosphoryl)propyl pendent groups on repeating pyrrolidinium units. Phosphonate ester hydrolysis in (CPE) (+) forms a pH-responsive cationic polyacid (CPA) (+). The (CPA) (+) is converted under pH-induced transformation into a polyzwitterion acid (±) (PZA) or a polyzwitterion/anion (±?) (PZAN) or a polyzwitterion/dianion (±=) (PZDAN) or a polyzwitterion/trianion (±?) (PZTAN).
