چکیده
|
A isatin schiff base,3-(4-hydroxyphenylimino)indolin-2-one,was synthesized and analyzed by nmr and ms. the inhibition and the mechanism of the title compound on the corrosion of high protective q235a steel in hcl solution were screened and discussed. the results indicated that it can inhibit the corrosion with moderate inhibition efficiency in different conditions,and the inhibition mechanism of the corrosion inhibiting may be mainly contributed to the adsorption. potentiodynamic polarization studies indicate that extracts are mixed-type inhibitors. while the title compound was companied with hexamethylenetetramine (hmta) and 1,4-dihydroxy-2-butyne (boz),the inhibition efficiency was enhanced effectively.
