Abstract: The raw materials 2-aminofluorene, pyridine-2,6-dicarbaldehyde and bromomalonaldehyde were used to synthesize pyridine-2,6-dicarbaldehyde-2-aminofluorene bis-Schiff base (A1) and bromopropanedialdehyde-2-aminofluorene bis-Schiff base (A2) by solution method. The structures of A1 and A2 were characterized by IR and FTMS. The corrosion inhibition performances of A1 and A2 were investigated by weight loss, electrochemical measurements and scanning electron microscope (SEM). The corrosion inhibition mechanisms of A1 and A2 were explored by quantum chemical calculation. The weight loss analysis showed that A1 and A2 exhibited the maximum inhibition efficiencies of 96.85% and 93.46% with the concentration of 1.0 mmol·L-1 in simulated circulating cooling water at 25 ℃, respectively. Electrochemical research showed that the two inhibitors have better corrosion inhibition efficiency. Both A1 and A2 followed Langmiur adsorption isotherm on the mild steel surface, and the value of ΔGadsθ are -27.02 kJ·mol-1 and -29.03 kJ·mol-1, respectively. These are mixed type adsorption and are anode type corrosion inhibitors mainly based on anode inhibition. Both A1 and A2 showed good corrosion inhibition performance in simulated circulating cooling water, and A1 has better inhibition property than A2.
