New Advances in Chemical Research, May 2021. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction.Application of 15804-19-0, In a article, mentioned the application of 15804-19-0, Name is Quinoxaline-2,3(1H,4H)-dione, molecular formula is C8H6N2O2
Self-assembly-based molecular structures have proven to be highly relevant to the development of soft materials. This work reports the synthesis, thermal behavior and computational analysis of two novel heterocyclic compounds with a non-symmetrical shape bearing a single long alkyl (C12) chain. The compounds 2-(4-dodecyloxy-phenyl)-1H-benzoimidazole, 1, with three-ring core mesogen with a more linear shape, and 1-dodecyl-1,4-dihydro-quinoxaline-2,3-dione, 2, with a condensed two-ring core with a more compact discotic shape, were obtained in good yields and investigated by polarized optical microscopy (POM) and differential scanning calorimetry (DSC) analysis. Benzimidazole derivative 1 was found to present liquid crystalline property, with a mesophase range from 85 to 177 C, as verified by POM and DSC, with a smectogenic polymorphism assigned as a SmB and a more organized unidentified SmX phase. On the other hand, although quinoxaline 2 did not show liquid crystal behavior, POM analysis indicated an interesting spherulitic packing pattern, typical of a columnar arrangement of the molecules by possible H-bond interactions. Computational results indicated that combining intermolecular hydrogen bonds and hydrophobic interactions lead to a non-planar lamellar model for benzimidazole 1, consistent with the smectic packing found in the liquid crystalline phase and a twist-type packing for compound 2, which is consistent with a spherulitic model.
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 15804-19-0 is helpful to your research. Application of 15804-19-0
