A silver halide light-sensitive photographic material comprising a support and provided thereon at least one silver halide emulsion layer containing a yellow dye-foming coupler having a formula [A] below and a high boiling organic solvent having a dielectric constant of not more than 6.0; ##STR...
The dielectric constant values of some protic and aprotic solvents in pure state are presented on the basis of MSA method, perturbation theory and Cluster expansion formulation. The calculations are made on statistical mechanical basis considering the cooperative effect and formation of cluster by H-bo...
Table II: Solvent miscibility table, cosolvent and antisolvent systems of acetaminophen. When the solubility values of acetaminophen and racemic (±)-ibuprofen at 25 °C were plotted against the dielectric constant of various solvents (see Table I) in which the APIs were solub...
For this model of solvent polarity, the dielectric function (ɛ–1)/(2ɛ + 1), developed for a diatomic oscillator in a dielectric continuum with macroscopic dielectric constant ɛ, was used (Fig. 4) [47]. Dielectric permittivities of solvents in binary mixtures being additive, the ...

Dependence of Ionic Mobility on Dielectric Constant of SolventBerns, D SFuoss, R M
For the solvents studied in this work, the free energy of pyridine protonation becomes more negative with decreasing solvent polarity, or dielectric constant. Computational investigations of the preferred structures of solvent-dependent specific acids are used to estimate the pore-phase proton transfer ...
of chlorobenzene. In this example, solvent polarity is measured by the dielectric constant (∈r), and the ∈rvalues for chlorobenzene, PA and EPA are 5.6, 6.9 and 5.4, respectively. An advantage to using PA and/or EPA in self-healing materials is their lower toxicity relative to ...
