  • Relation Between Dielectric Constant and Solubilization of Polar Substances in Various Chlorinated Solvents

抄録

The solubilization of water in various surfactant solutions of chlorinated solvent were investigated in relation to the dielectric constant (ε) of each solvent. As an example of the application of solubilization of polar substances, contamination tests were carried out on cotton and acrylic fabrics by acid dye (Azure Blue V) .<BR>1) A value of ε was unaffected by the addition of surfactants or water into the solvent, while the conductivity (G) increased by the addition of sodium di-2-ethylhexyl sulfosuccinate (DOS), especially in the solvent of high ε.<BR>2) The higher a value of ε, the greater the solubility of water in each solvent. DOS had a high ability to solubilize water and the ability showed minimum at ε ≈ 5, whereas polyoxyethylene monostearate (EOS) showed little water solubilizing effect.<BR>3) The degree of contamination (DOC) by Azure Blue V depended on ε of each solvent and it showed minimum at ε ≈ 7. DOS had a lowering effect of DOC and the effect became more remarkable in the solvent of high ε.
