Abstract
Derivatives with the formulas [Na4Ca(PO3)6]n, [Na4Ba(PO3)6]n, and [Na4Zn (PO3)6]n have been prepared by heating together mixtures of NaH2PO4·2H2O, CaO (or Ba(OH)2 ·-8H2O or ZnO), and (NH4)2 HPO4 in the molar ratios of 4:1:2 at 700 and 800°C. for 1 hr. The number-average molecular weights of these derivatives have been measured by the end group titration method. Their conductance has been measured in aqueous solution of varying concentration, and their properties compared with those of Graham's salt (NaPO3)n prepared under similar conditions.
