Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 100-48-1, Name is Isonicotinonitrile, molecular formula is , belongs to pyridine-derivatives compound. In a document, author is Kaya, Ismet, HPLC of Formula: C6H4N2.
Synthesis and characterization of Schiff base, Co(II) and Cu(II) metal complexes and poly(phenoxy-imine)s containing pyridine unit
In the first stage, two different Schiff base ligands were prepared by the condensation of 2-amino-5-bromopyridine and 2-amino-5-chloropyridine with salicylaldehyde in methanol at the molar ratio of 1:1. Ligands: C12H9ON2Br (L1), C12H9ON2Cl (L2). In the second stage, four different metal complexes were obtained from Schiff bases with Co(OAc)(2)4H(2)O and Cu(OAc)(2)2H(2)O Molecular formulas of the metal complexes obtained were [Co-2(L1)(2)(H2O)(OCH3)]H2O, [Cu-2(L1)(2)(H2O)(OCH3)]H2O, [Co-2(L2)(2)(H2O)(OCH3)]H2O and [Cu-2(L2)(2)(H2O) (OCH3)] H2O. In the third stage, ortho-vanillin (VAN) was polymerized via oxidative polycondensation in aqueous alkaline medium with air as oxidant. Then, poly(phenoxy-imine)s were synthesized from condensation reactions of poly (ortho-vanillin) (PVAN) with 2-amino-5-bromopyridine and 2-amino-5-chloropyridine in THF medium at 60 degrees C. All synthesized compounds were characterized by spectral and electrochemical techniques. Thermal properties of the compounds were determined by TGA-DTA and DSC analyses. The molecular weights of the polymers were calculated from SEC analyses. Poly[2-((5-bromopyridin-2-yl-imino)methyl)-6-methoxyphenol] (PVANBr) and poly[2-((5-chloropyridin-2-yl-imino)methyl)-6-methoxyphenol] (PVANCl) were determined to have electrical conductivity of 10-3 S cm(-1). Electrochemical band gaps (Eg’) of PVANBr and PVANCl were calculated as 2.10 and 1.95 eV, respectively. Initial decomposition temperatures of [Co-2(L1)(2)(H2O)(OCH3)]H2O, [Cu-2(L1)(2)(H2O)(OCH3)]H2O, [Co-2(L2)(2)(H2O)(OCH3)]H2O and [Cu-2(L2)(2)(H2O) (OCH3)]H2O were found to be 309, 271, 305 and 259 degrees C, respectively.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 100-48-1, in my other articles.
