The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. COA of Formula: https://www.ambeed.com/products/1439-36-7.html, 1439-36-7, Name is 1-(Triphenylphosphoranylidene)propan-2-one, SMILES is CC(C=P(C1=CC=CC=C1)(C2=CC=CC=C2)C3=CC=CC=C3)=O, in an article , author is Shafe-Mehrabadi, Sayed Rasul, once mentioned of 1439-36-7.
Nanostructured SiO2-H2SO4 as an efficient and nano catalyst for one-pot synthesis of phtahalazines via three-component condensation of an aromatic or aliphatic aldehyde, malononitrile and 5-amino-2,3-dihydro-phthalazine-1,4-dione. Nanostructured SiO2-H2SO4 was synthesized and characterized via FT-IR and SEM techniques. It is rapid and efficient catalyst for one-pot synthesis of the biologically important 3,9-diamino-5,10-dioxo-1-aryl-5,10-dihydropyrazolo[1,2-b]phthalazine-2-carbonitrile derivatives. The significant features of this methodology are nontoxic catalyst, short reaction time (10 min), recyclability, low catalyst loading, green organic solvent (ethanol), and avoiding tedious purification step.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 1439-36-7, you can contact me at any time and look forward to more communication. COA of Formula: https://www.ambeed.com/products/1439-36-7.html.
