Zusammenfassung: | Purpose - To evaluate the effect of synthesised calixarenes as new inhibitors on the corrosion of steel in HCl media at various temperatures.Design methodology approach - Calixarenes have been synthesised and tested as corrosion inhibitors. Gravimetric technique and potentiodynamic polarisation and impedance spectroscopy methods were used.Findings - Calixarenes exhibited a good inhibition. Their efficiency decreases slightly with temperature.Research limitations implications - It was found that the inhibition efficiency increases with the concentration of inhibitors to reach 92 per cent at 10−4M.Practical implications - The efficiency of calixarene derivatives increases with the concentration and falls slowly with temperature to attain 84 per cent at 353 K range. Calixarenes can be used in chemical cleaning and pickling processes.Originality value - The originality of this work is to find an inhibitor to give protection close to 100 per cent. |
