| Abstract: | Dextrofosfomysin levophenethylamine salt was used as the outset raw material to prepare HEHSP-(Na)2,a new corrosion inhibitor containing sulfur.The inhibition efficiency of HEHSP-(Na)2 was tested by weight loss and electrochemistry polarization methods.And the absorbance of HEHSP-(Na)2 on Q235 carbon steel was preliminarily discussed.The results show that HEHSP-(Na)2,as a complex inhibitor,gives nice inhibition efficiency on Q235 carbon steel in hydrochloric acid medium,its adsorption conforms to Flory-Huggins uniform temperature equation,which is multi-molecular layer layer adsorption,and belongs to physical adsorption. |
