Abstract

In this study, the usage of the inhibitor  1-Methylisoquinoline with various concentrations from 100-600 ppm, and its influence on corrosion of mild steel 1M hydrochloric acid and the results proved that this type of inhibitors as efficient and good quality , and efficiency increases with the concentration of the inhibitor in temperature of  303 K , and whenever increased temperature of 313-323 K decreased efficiency and was used weight loss and hydrogen gas evolution methods , and the activation energy enlarged with increasing inhibitor concentration  as well as energy enthalpy and free energy of adsorption ,adsorption be physically in low concentrations ,while mixed type  in high concentrations.
