摘要: Abstract This paper reports the partition coefficients for neutral and anionic species of homologous series alkyl p -hydroxybenzoates (from methyl to pentyl) with CTAB micelles at 15, 25, 35°C. These values are compared literature data same compounds some discrepancies found attributed solute ionization in earlier results. Solute K a also reported presence cationic, anionic, nonionic micelles, accordance qualitative Hartley's rule. effects increase hydrophobicity due stronger interaction micelles. The Δp related using models, allowing us evaluate PPIE selectivity constants exchange between anions Br − Both slightly decrease as temperature increases, agreement current view hydrophobic interaction. effect solutes on CMC is ascribed intensity their ionization.
