o‐iodoxybenzoic acidoxidationproton affinityNot just a pretty oxidant! IBX (1-Hydroxy-1,2-benziodoxol-3(1H)-on-1-oxide), an important oxidant in organic synthesis, is shown to be relatively acidic on the organic scale. The pKa value and proton affinity of IBX were determined both in ...
Regression analyses demonstrated that all of the pKa scales obtained in four RTILs are linearly correlated to each other with an R value better than 0.996. These scales are also correlated well with the pKa values in DMSO and with the corresponding gas-phase acidities with regression coefficients...
The adsorption of benzoic acid and its derivatives to swollen chitosan beads increased with decreasing pKa value, except for those compounds having a hydroxyl group in the aromatic ring. The hydroxyl group had the ability to stimulate adsorption, this effect being stronger than that of pKas. The...
The pKa of benzoic acid is 4.20(5), indicating that this compound will exist in anion form in the environment and anions generally do not adsorb more strongly to organic carbon and clay than their neutral counterparts(6). Freundlich adsorption constants of 0.23, 0 and 0 were reported using ...
