One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 402-49-3, Name is 1-(Bromomethyl)-4-(trifluoromethyl)benzene, formurla is C8H6BrF3. In a document, author is Hasaninejed, Alireza, introducing its new discovery. Formula: https://www.ambeed.com/products/402-49-3.html.
A green practical method for the efficient synthesis of 2H-indazolo[2,1-b]phthalazine-1,6,11(13H)-triones using sulfuric acid-modified polyethylene glycol-6000 (PEG-OSO3H) as an eco-friendly polymeric catalyst from the four-component condensation reaction of phthalic anhydride, hydrazinium hydroxide, 1,3-cyclohexanedione or 5,5-dimethyl 1,3-cyclohexanedione (dimedone) and aromatic aldehydes under solvent-free conditions at 80 degrees C is described. This approach allowed the environmental impact factor (E-factor) to be minimized. (C) 2012 Elsevier B. V. All rights reserved.
