| Abstract: | Conclusions The dissociation constnats of cyclic oxygen-containing phosphorus acids in absolute alcohol were measured by potentiometric titration in charge transfer circuits.For acyclic phosphorus acids ABPOOH, there is a Brönsted dependence in pK(EtOH)-pk(H2O) coordinates, which does not apply to 1,3-alkylenephosphoric acids, while in the pK(MeNO2)pK(EtOH) coordinates there is a uniform Brönsted dependence for all the acids.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 6, pp. 1244–1248, June, 1987. |
