摘要：New cyclotriphosphazene, namely Hexa propylene glycol cyclotiphosphazene (HPGCP) was synthesis and their inhibitive action against the corrosion of carbon steel in 1 M HCl solution were investigated at room temperature by various corrosion monitoring techniques, such as weight loss, potentiodynamic polarization curves, and electrochemical impedance spectroscopy (EIS) methods. The Hexa glycol cyclotriphosphazene (HPGCP) outcome of solvolysis of Hexa glycidyl cyclotriphosphazene (HGCP) in basic solution. The compounds were characterized using spectroscopic techniques (FTIR).The results showed that the investigated Hexa propylene glycol cyclotiphosphazene (HPGCP) are good corrosion inhibitors for carbon steel in 1 M HCl medium, their inhibition efficiency increased with inhibitor concentration. Polarization studies showed that both studied inhibitors were of anodic type inhibitor in 1 M HCl.The adsorption of inhibitors on the carbon steel surface obeys Langmuir adsorption isotherm. Scanning electron microscopy (SEM) was performed and discussed for surface study of uninhibited and inhibited carbon steel samples.
