Several substituted imidazolidine-2,4-thiones were shown electrochemically to produce up to a 40-fold acceleration of iron corrosion by acids. Possible mechanisms were considered on the behavior of adsorbed imidazoldines whose molecular structure and bond polarization can lower the activation energy of proton transfer from the solution to the electrode.

Abstract
Several substituted imidazolidine-2,4-thiones were shown electrochemically to produce up to a 40-fold acceleration of iron corrosion by acids. Possible mechanisms were considered on the behavior of adsorbed imidazoldines whose molecular structure and bond polarization can lower the activation energy of proton transfer from the solution to the electrode.
