摘要：
A halogen-free quaternary ammonium-based ionic liquid functionalized with benzotriazole, BTA-16-BTA, was synthesized. Its anticorrosion effects on Q235 steel were evaluated in two different acids (6 M HCl or 1 M H3PO4) by weight loss and electrochemical tests. BTA-16-BTA shows the best performance at 30 degrees C with the highest inhibition efficiencies of 98.84% in 6 M HCl and 96.40% in 1 M H3PO4. The adsorption behavior of BTA-16-BTA molecules on Q235 steel in HCl solution obeys the Langmuir isotherm with an adsorption energy of about -40 kJ<middle dot>mol(-1), which implies chemisorption. Quantum chemistry calculation indicates that the chemical adsorption originated from the injection of pi-electrons from inhibitor molecules into empty 3d orbitals of Fe atoms. The tight adsorption of inhibitor molecules and associated dehydration of the steel surface promoted the corrosion inhibition in HCl solutions. In H3PO4 solutions, passivation by phosphate anions and adsorption of inhibitor molecules contributed synergistically to the excellent anticorrosion performance.
