Haglund, Aasa C. published the artcileHydrophobic and polar contributions to solute affinity for a highly crosslinked water-swollen (sephadex) gel, SDS of cas: 6972-05-0, the publication is Journal of Polymer Science, Polymer Letters Edition (1980), 18(4), 271-9, database is CAplus.
Adsorption affinity was studied on Sephadex gels, which are commonly used in gel chromatog. The studies support the hypothesis of a hydrophobic interaction in the adsorption of nonpolar and weakly polar aliphatic solutes, suggest that ¦Ð electrons in the solute promote affinity, suggest that a reduced affinity in hydroxyl derivatives of paraffins is caused by lowered hydrophobicity due to the polarity of the OH group, show that there are stringent demands on solute structure if mol. sieve behavior is to be manifest, and also show that, whereas the gel has an affinity for hydrocarbons, both aliphatic and aromatic, it does not prefer the latter; a higher aromatic affinity requires an addnl. condition. The studies included distribution coefficients, heat of adsorption, entropy of adsorption, and free energy of adsorption. The compounds studied included hydrocarbons, aldehydes, alcs., phenols, ketone, amides, urea derivatives, and thiourea derivatives
