The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.14098-44-3, Name is Benzo-15-crown-5, molecular formula is C14H20O5. In a Article，once mentioned of 14098-44-3, SDS of cas: 14098-44-3
The effect of {(1-x)N,N-dimethylacetamide (DMA) + xH2O} on the thermodynamics of benzo-15-crown-5 (B15C5) ether/Na+ complex formation at 298.15 K was investigated. B15C5/Na+ complexes were enthalpy stabilized and entropy stabilized in the mixed solvent DMA-water. The benzene ring was unable to form complexes with Na+ in {(1-x)DMA + xH2O}, {(1-x)dimethyl sulfoxide (DMSO) + xH2O}, and {(1-x)N,N-dimethylformamide (DMF) + xH2O}. A simple model was developed to describe the relationship between the thermodynamic functions of complex formation of crown ethers with Na+ and the structural and energetic properties of the mixed solvent. The effect decreased in the following series of solvents: DMA > DMF > DMSO or with the decrease in their hydrophobic properties. The enthalpy-entropy compensation for the complex formation process between the crown ethers (15C5 or B15C5) and Na+ appeared in the mixed water-organic solvent within the whole range of mixed solvent composition, if the structure of the mixed solvent was not disturbed by specific interactions between the molecules of crown ethers and those of mixture components.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 14098-44-3 is helpful to your research., SDS of cas: 14098-44-3
