Electric Literature 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
[60]- and [70]fullerenes have been shown to form 1:1 molecular complexes with a series of crown ethers, namely, (i) 4a¿²-nitrobenzo-15-crown-5 (1). (ii) dibenzo-24-crown-8 (2), (iii) dibenzo-30-crown-10 (3), (iv) benzo-15-crown-5 (4), and N,Na¿²-dibenzyl-1,4,10,13-tetraoxa-7, 16-diazacyclooctadecane (5) in CCl4 medium by the NMR spectrometric method. Formation constants (K) of the complexes have been determined from the systematic variation of NMR chemical shifts of specific protons of the crown ethers in the presence of [60]fullerene and [70]fullerene. The magnitudes of K indicate that the crown ethers 2 and 3 form inclusion complexes with [60]fullerene but not with [70]fullerene.
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., Electric Literature of 14098-44-3
