Multinuclear Nmr Studies of Alkali Ions in Nonaqueous Solvents
Nuclear magnetic resonance of alkali elements is a very sensitive probe of the immediate chemical environment of an alkali ion in solutions and can be used to study ion-ion, ion-solvent and ionligand interactions. In particular, this technique has been used to determine contact ion pair formation constants, to compare solvating abilities of different solvents and to study the thermodynamics of ...
متن کاملNMR Study of Benzo-15-Crown-5 Complexes with 7Li+ and 133Cs+ Ions in Nonaqueous solvents
Complexes of benzo-15-crown-5 macrocycle with Li+ and Cs+ ions were investigated by 7Li and 133Cs NMr in a number of nonoqueous solutions. The resulting 1:1 complex with Li+ ion was found to be much more stable than that with Cs+ ion. With the exception of pyridine solutions the stabilities of the complexes varied inversely w...
متن کاملComplexation Study of Alkali Metal Ions by Crown Ether Derivatives in Nonaqueous Solvents by Potentiometric Methods
The formation and stability of alkali metal complexes with crown ethers containing an anthraquinone unit has been investigated in methanol and acetonitrile solutions by potentiometric methods. Complexes of 1:1 stoichiometry were observed for all the studied systems; 2:1 complexes were only detected for the larger alkali cations (Rb and Cs) and with the ligand with the larger macrocyclic cavity ...

متن کاملWater in nonaqueous solvents*
The possibility and usefulness of sinple liquid models is reported. The importance of van der Waals forces for liquid water and aqueous solutions is discussed and compared with the solubility of water in nonpolar solvents and as well as of nonpolar solvents in water. Both systems could be understood as equilibrium of few water monomers. The network of H-bonded water molecules seems to be less i...
