These research results belong to Bondarev, N. V.. Product Details of 33100-27-5 The article mentions the following:
An approach to predict the stability constants of coronates from the properties of solvents, cations, and crown ethers has been developed based on exploratory and neural network methods for math. modeling of equilibrium in solutions Exploratory (factor, cluster, discriminant, canonical, decision trees), regression, and neural network (supervised and Kohonen network) models of the stability of crown ethers (12C4, 13C4, 14C4, 15C4, 15C5, 18C6, 21C7, 24C8, B12C4, B15C5, CH15C5, CH18C6, DCH18C6, DCH21C7, DB18C6, DB21C7, DB24C8, DB27C9, and DB30C10) complexes with cations of alkali (Li+, Na+, K+, Cs+, Rb+) and alk.-earth (Ca2+, Sr2+, Ba2+) metals in aqueous and non-aqueous (acetone, acetonitrile, DMSO, methanol, pyridine, DMF, dioxane, propylene carbonate, 1,2-dichloroethane, and nitrobenzene) solutions have been developed according to the properties of solvents (diameter of solvent mol., Kamlet-Taft parameter, Dimroth-Reichardt parameter, dielec. constant), crown ethers (Balaban topol. index), and cations (cation diameter) at 298.15 K.1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5Product Details of 33100-27-5) was used in this study.
1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5) is a member of crown ether Ligands. Crown-ethers are macrocyclic polyethers capable of forming host-guest complexes, especially with inorganic and organic cations. Crown-ethers can incorporate protonated primary amine compounds by formation of ion-dipole bonds with the oxygen atoms of the chiral selector. Crown-ethers have been widely used for the separation of several pharmaceuticals both in aqueous and non-aqueous media. Product Details of 33100-27-5
