Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics, 5308-25-8, Name is 1-Ethylpiperazine, SMILES is CCN1CCNCC1, belongs to piperazines compound. In a document, author is Moghzi, Faezeh, introduce the new discover, Name: 1-Ethylpiperazine.
0D to 3D Pr-III metal-organic networks crystal engineered for optimal iodine adsorption
Four new praseodymium(III) metal-organic compounds varying in dimensionality from 0D to 3D have been designed and synthesized based on N-heterocyclic polycarboxylic acids, including pyridine-2,6-dicarboxylic acid (H(2)pydc) and pyrazine-2,3-dicarboxylic acid (H(2)pzdc). Altering the concentration of piperazine (pip, ancillary ligand) enables control over the dimensionality of the compound by switching between the 0D [H(2)pip][Hpip][Pr(pydc)(3)]center dot 4H(2)O (I) and the 1D {[Pr(pydc)( Hpydc)(H2O)(2)]center dot 4H(2)O}(n) (II) coordination polymer (CP). Upon replacing H(2)pydc with H2pzdc, CP II is converted to the 2D CP [Pr(pzdc)(Hpzdc)(H2O)(3)](n) (III) and using the metalloligand [Zn(Hpzdc)(2)(H2O)(2)](2-) the 3D heterometallic CP {[Pr2Zn(pzdc)(4)(H2O)(6)]center dot 2H(2)O}(n) (IV) is formed. Compound IV shows high stability in the absence of uncoordinated solvent molecules and is stable up to 400 degrees C, even in the presence of humidity. Therefore, IV was utilized for iodine adsorption in the vapour phase and in the presence of humidity. The results confirm the remarkable potential of IV for reversible adsorption of iodine vapour.
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 5308-25-8 is helpful to your research. Name: 1-Ethylpiperazine.
