SOLVATION PARAMETERS OF LEAD ACETATE IN MIXED WATER-N,N-DIMETHYLFORMAMIDE MIXTURES AT 298.15 K
Journal Title: Analele Universitatii din Bucuresti. Chimie - Year 2010, Vol 19, Issue 1
Abstract
The molar solubility of lead acetate (LA) in mixed DMF-H2O solvents was measured at 298.15 K. From the molar solubilities the solvation parameters, Debye Huckel constants A, B, activity coefficient, solubility products, free energies of solvation and transfer free energies for the interaction of (LA) from water as reference solvent to mixed (DMF-H2O) solvents were evaluated. All the solvation parameters were discussed.

ELECTRIC FIELD EFFECT ON OPTICAL DICHROISM OF SOME AZODYES DISSOLVED IN COMPENSATED CHOLESTERIC LIQUID CRYSTAL
In the paper are presented the results obtained in the study of the optical dichroism of some azodyes dissolved in a compensated mixture of cholesteryl chloride and cholesteryl-nonanoate under the electric field action....
CONSTITUENTS FROM FERONIA LIMONIA
The root and stem bark of Feronia limonia yielded 5, 7-dihydroxy-3', 4'-dimethoxy -6, 8-di (3-methylbut-2-enyl) flavanone along with several known compounds viz., stigmasterol, friedelin, β-sitosterol-3-O-β-D-glucopyran...
A DSC STUDY OF gamma-AMINOBUTYRIC ACID GAMMA IRRADIATED
The behaviour on heating of irradiated with gamma rays and non-irradiated γ-amino-butyric acid (γ-AMB) was investigated by means of differential scanning calorimetry. γ-AMB decomposes before melting.
