Solvent Effects on Extraction of Sodium Picrate with 15-Crown-5. The Determination of Ion-Pair Formation Constant of Crown Ether-Metal Salt 1:1:1 Complex in Water
In order to determine the ion-pair formation constant of a crown ether-metal salt complex (1:1:1) in water, an equation is derived from the regular solution theory.Then, the theoretical predictions are verified experimentally by solvent extraction with 15-crown-5 (15C5), sodium picrate (NaA), and various organic solvents of low dielectric constant.The partition constants of 15C5 and the actual overall extraction constants of NaA with 15C5 were determined at 25 +/- 0.2 deg C.The partition constants of the Na(15C5)A complex are calculated from these data, the literature value for the complex-formation constant of Na(15C5)+ in water, and the ion-pair formation constant (KNa(15C5)A) in water determined in this study (log KNa(15C5)A = 4.09 +/- 0.23 at 25 deg C).The distribution behavior of 15C5 and Na(15C5)A is explained by the regular solution theory.The obtained molar volumes V/cm3 mol-1 and solubility parameters delta/cal1/2 cm-3/2 are as follows; V15C5 = 189 +/- 34, VNa(15C5)A = 215 +/- 46, delta15C5 = 12.0 +/- 0.1, and deltaNa(15C5)A = 12.0 +/- 0.1.
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 33100-27-5 is helpful to your research., Synthetic Route of 33100-27-5
