A. Frignani et al., EVALUATION OF THE INHIBITION EFFICIENCY OF ACETYLENIC HALO-DERIVATIVES BY ELECTROCHEMICAL METHODS AND SOLUTION ANALYSIS, Journal of Applied Electrochemistry, 25(4), 1995, pp. 371-375
The behaviour of some 3-methyl-1-butyne halo-derivatives towards Armco
iron corrosion in 0.5 M H2SO4 was examined by the analysis of dissolv
ed iron and electrochemical methods. Their inhibitive performance was
determined in relation to the introduced halogen atom with respect to
the duration of the tests and temperature. At the same time, these eff
ects were compared to those of 1-octyn-3-ol. In general, the results o
f the electrochemical methods were found to be in good agreement with
those of solution analysis. The possibility of obtaining reliable corr
osion data from electrochemical impedance spectroscopy measurements by
simply applying the Stern-Geary equation is discussed.
