Thermodynamic ionization constants of para-substituted N-phenyl-benzohydroxamic acids.
Thermodynamic ionization constants of para-substituted N-phenylbenzohydroxamic acids have been determined in dioxan-water mixtures at 35 degrees . The plot of mole fraction of dioxan vs. pK(a) is linear at this temperature, whereas that of pK(a)vs. 100/D is linear over a narrow range of dielectric constants (D) but at higher mole fraction of dioxan is influenced by non-electrostatic factors.
