Reference of 288-14-2, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 288-14-2, molcular formula is C3H3NO, introducing its new discovery.
Preparation of CuO/SiO2catalyst has been done via sol-gel method using copper nitrate solution and TEOS as precursors. Several instruments such as FT-IR, SEM, EDAX, XRD and particle sizer were employed to characterize the obtained material. Then, CuO/SiO2 catalyst was successfullyusedin the synthesis of three curcumin derivatives, 4,4′-((1E,1?E)-(1H-pyrazole-3,5-diyl)bis(ethene-2,1-diyl))bis(2-methoxyphenol) (Compound 1), 4,4′-((1E,1?E)-(1- phenyl-1H-pyrazole-3,5-diyl)bis(ethene-2,1-diyl))bis(2-methoxyphenol) (Compound 2) and 4,4′-((1E,1?E)- (isoxazole-3,5-diylbis(ethene-2,1-diyl))bis(2-methoxyphenol) (Compound 3) with good yields.
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 288-14-2 is helpful to your research. Reference of 288-14-2
