STUDY OF THE CORROSION INHIBITORS PROPERTIES OF WATER-SOLUBLE NITROGEN CONSISTING ALKENYLPHENOLS DERIVATIVES

1-(2-allylphenoxy)butyl-4-N-pyridinium bromide and 1(2-propenylphenoxy)butyl-4-N-pyridinium bromide were synthesized and investigated as corrosion inhibitors steel st. 3. Their corrosion inhibition property was investigated in aqueous-salt containing solution hydro-carbonic and H2S. For this purpose, a serious of techniques such as gravimetric method measurement, scanning electron microscope (SEM-XL-30) were used. Some thermodynamic parameters of corrosion process (∆Gads., ∆H0ads., ∆S0ads.) were determined. Results showed that synthesized compounds at the concentrations 50–150 mg l-1 have anticorrosion activity 62–96%.
