Application of 14098-44-3, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 14098-44-3, Name is Benzo-15-crown-5, molecular formula is C14H20O5. In a Article，once mentioned of 14098-44-3
With ethyl lactate as an optically active precursor and with employment of Williamson reactions, three isomeric and axially symmetric dimethylbenzo-15-crown-5 ethers were prepared and characterized: (5R,15R)-5,15-dimethyl-5,6,8,9,11,12,14,15-octahydrobenzo-1,4,7,10,13-pentaoxacyclopentadecin and the (6S,14S)-6,14-dimethyl and (8S,12S)-8,12-dimethyl isomers, termed the alpha, beta, and gamma isomers, respectively.The circular dichroism spectra of the ethers and their complexes with Na+ in CH3OH have been determined and interpreted in terms of the gross overall orientationof the macrocycle in relation to the aromatic ring.The behavior of the gamma-isomer with Ba2+ and with low ratios of K+ suggests dominance of 2:1 (sandwich) complexes.
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 14098-44-3 is helpful to your research., Application of 14098-44-3
