Hou, Yanggao;Zhu, Limeng;He, Kang;Yang, Ze;Ma, Sicai;Lei, Jiaheng published 《Synthesis of three imidazole derivatives and corrosion inhibition performance for copper》. The research results were published in《Journal of Molecular Liquids》 in 2022.Synthetic Route of C6H4N2 The article conveys some information:
Three imidazole derivatives I [X = 3-pyridyl, 2-pyrazinyl, 2-pyrimidinyl], were synthesized. The structure of these compounds was confirmed by LC-MS, 1H NMR, 13C NMR and FTIR spectra. The inhibition performance in 3.5 wt% NaCl was investigated by electrochem. measurement and surface anal. Results showed that the corrosion efficiency of I [X = 3-pyridyl] (95.93%) was higher than I [X = 2-pyrazinyl] (69.61%) and I [X = 2-pyrimidinyl] (20.46%), which was consistent with the adsorption energy calculated by mol. dynamics simulation. The corrosion inhibition mechanism could be explained by the metal-organic polymer film formed on the copper surface: on the one hand, the π-system formed by aromatic rings is tightly adsorbed on the copper substrates; on the other hand, the nitrogen atoms in the imidazole ring are coordinated with the metal ions in solution to form metal-organic polymer which could improve the compactness of the hydrophobic film.3-Cyanopyridine (cas: 100-54-9) were involved in the experimental procedure.
3-Cyanopyridine(cas: 100-54-9) is an antimicrobial agent that can be used in the treatment of infectious diseases.Synthetic Route of C6H4N2 It has been shown to be effective against a variety of bacteria, including methicillin-resistant Staphylococcus aureus (MRSA) and Streptococcus pneumoniae.
