Application of thiazole and triazole compounds in carbon steel corrosion protection

Application of thiazole and triazole compounds in carbon steel corrosion protection

Inhibitory effect of 2-mercaptobenzothiazole (MBT) and 1,2,3-benzotriazole (BTA) on corrosion of carbon steel in 1.0 M HCl and seawater sample respectively has been studied using weight loss method. All measurements show that inhibition efficiencies of BTA and MBT increased with increase in inhibito...

All measurements show that inhibition efficiencies of BTA and MBT increased with increase in inhibitor concentration and temperature in 1.0 M HCl and seawater sample. The results of the investigation show that the compound BTA and MBT have fairly good inhibiting properties with inhibition efficiencies of 98.24% for BTA and 92.98% for MBT in seawater sample while 87.49% for BTA and 30.15% for MBT in 1.0 M HCl, at 90 °C.
