Popis: | The distribution ratios of some heterocyclic N-oxides and N-basesbetweenaqueousand benzene phaseshave been determined. Such ratios appear to be independent of the total base concentration over the range investigated. The partition of an N-oxide into benzene is about 1000 times less than its analogous N-base. The pKa values of the heterocyclic N-oxides conjugate acids have been determined by the partition technique. |
