Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 693-98-1, Name is 2-Methyl-1H-imidazole, SMILES is CC1=NC=CN1, belongs to imidazoles-derivatives compound. In a document, author is El-Haddad, Mahmoud N., introduce the new discover, Safety of 2-Methyl-1H-imidazole.
Electroanalytical, quantum and surface characterization studies on imidazole derivatives as corrosion inhibitors for aluminum in acidic media
In this study, the effect of imidazole derivatives on the inhibition of aluminum corrosion in 0,5 M HCl has been studied using potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and electrochemical frequency modulation (EFM) measurements. The results show that all imidazole derivatives are good inhibitors, and inhibition efficiency follows the order: 8> A. Polarization curves demonstrated that the imidazole derivatives were of mixed-type inhibitors. The adsorption of each inhibitor on aluminum surface obeys Frumkin adsorption isotherm. Surface morphology studies were done using scanning electron microscopy (SEM) to characterize the film formed on aluminum surface. Quantum chemical calculations show that imidazole derivatives can adsorb on the aluminum surface through the nitrogen atoms as well as it-electrons in the imidazole ring. (C) 2015 Elsevier B.V.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 693-98-1 is helpful to your research. Safety of 2-Methyl-1H-imidazole.
