On the metal sewage treatment constructions (Chernihiv, Ukraine) a biofilm is formed, which is corrosive because of the number of sulfate-reducing bacteria (107 cell/cm2). By affecting sulfate-reducing activity of microorganisms, pyridinium chlorides at the concentration of 0.5 g/l were revealed to provide St3ps steel inhibition efficiency of up to 98.7% under the corrosion caused by biofilm bacteria. In the experiment, the researchers used many compounds, for example, Pyridinehydrochloride (cas: 628-13-7Category: pyridine-derivatives).
Pyridinehydrochloride (cas: 628-13-7) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of 閳?8.7 鑴?10閳? cm3璺痬ol閳?.The molecular electric dipole moment is 2.2 debyes. The standard enthalpy of formation is 100.2 kJ璺痬ol閳? in the liquid phase and 140.4 kJ璺痬ol閳? in the gas phase. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C閳ユ弻 in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.Category: pyridine-derivatives
