Abstract :
A new 2,3-(2-alkylthio)-6,7-bis(2-alkylthio)TTF was prepared, characterized by NMR spectroscopy and its anti-corrosion properties were studied and observed. The anticorrosion property of 2,3-(2-alkylthio)-6,7-bis(2-alkylthio)TTF has been studied as a possible source of non-toxic corrosion inhibitor of mild steel in 1M HCl. The techniques included weight loss method, electrochemical measurements, and quantum chemical calculations. Dependence of corrosion inhibition efficiency on various parameters was examined and it was seen that increase in concentration of inhibitor lead to increase in inhibition efficiency. The dipole moment and E_HOMO-E_LUMO influence the inhibition efficiency which was observed by using quantum chemical studies.
