Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 623-25-6, Name is ¦Á,¦Á’-Dichloro-p-xylene, SMILES is ClCC1=CC=C(CCl)C=C1, belongs to phthalazines compound. In a document, author is Nikoorazm, Mohsen, introduce the new discover, Product Details of 623-25-6.
Synthesis and characterization of Ni(II)-Vanillin-Schiff base-MCM-41 composite as an efficient and reusable nanocatalyst for multicomponent reactions
An efficient heterogeneous catalyst (Ni(II)-Vanillin-Schiff base-MCM-41) has been synthesized by immobilization of nickel(II)-vanillin complex on MCM-41 nanostructure and characterized by XRD, TGA, BET, EDS, SEM, ICP-OES, TEM and FT-IR spectroscopy. The catalytic activity and stability of the prepared compound has been studied in some multicomponent reactions with polyhydroquinoline, 1H-indazolo [1,2-b] phthalazine-trione and 2,3-dihydroquinazolin-4(1H)-one derivatives under mild condition reactions. All the reactions were carried out in the presence of water as the solvent and under solvent-free conditions. The simple work up, mild conditions, excellent yield, inexpensive and non-toxic catalyst; makes this protocol both attractive and economically viable. More importantly, this catalyst can be reused several times without any significant loss of its catalytic activity.
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 623-25-6 is helpful to your research. Product Details of 623-25-6.
