Abstract BIA, BIOHA, BIMHA and BIMMA were synthesized in the laboratory and their influence on the inhibition of corrosion of A3 steel in 1 mol/L HCl solution was studied by weight loss and electrochemical measurements. The obtained result showed that four compounds were good inhibitors and performed pretty inhibiting efficiency for A3 steel in 1 mol/L HCl solution. The inhibition efficiency of the tested compounds was found to decrease as follows: BIA>BIMMA>BIOHA>BIMHA. It was found that the inhibition efficiency increases with an increase in the tested compounds concentration but decreases with an increase in temperature. Compounds were imxed - type corrosion inhibitors, but its inhibition of the anodic reaction is a little better. Thermodynamic paarameters such as adsorption heat, adsorption entropy and adsorption free energy were obtained from experimental data of the inhibition process at four temperatures ranging from 40℃ to 70℃. The adsorption processes are exothermic reaction and belong to physical adsorption. The langmuir isotherm is followed.
