Reference 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
Acylation reactions of benzocrown ethers with N-phthalimido-protected derivatives of beta-alanine and 11-aminoundecanoic acid, respectively, were investigated in acid catalysis by using the Eaton reagent. Deprotection of the obtained compounds by hydrazinolysis afforded derivatives with free amino groups the reaction of which with one or two equivalents of 2,4,6-trisubstituted pyrylium salts furnished pyridinium derivatives. All these new benzocrown ether derivatives were characterized by elemental analysis and IR and NMR spectroscopy. VCH Verlagsgesellschaft mbH, 1996.
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., Reference of 14098-44-3
