Chemical synthesis methods and IR spectrometry studies are reported for an organic triphosphate (NH3C6H4COOH)3H2P3O10.3H2O and its anhydrous new form NH3C6H4COOH)3H2P3O10. The hydrate compound (NH3C6H4COOH)3H2P3O10.3H2O was synthetized by the ion-exchange resin method. The dehydration of (NH3C6H4COOH)3H2P3O10.3H2O leads at 130°C to (NH3C6H4COOH)3H2P3O10 crystallizing in the triclinic system with space group P 1 (Z = 2) [a = 14.566(6) Å, b = 6.866 (1) Å, c = 6.445 (6) Å, α = 112.36 (3) °, β = 94.51 (1) °, γ = 95.94(7) °, and V = 587.98 (1) Å3 ]. Merit’s figures are M (10) = 91.9 and F (10) = 55.6 (0.0032, 56). Its thermal behavior and kinetic study were studied by using thermal analyses TGA and DTA techniques between 25 and 600°C.

Resin Method

In this paper, nanometer MgO powder was prepared by using MgCl2•6H2O as the raw material, and environmental benign strong-base anion exchange resin as the induced-precipitation regent. The influence of the concentration of MgCl2 solution, drying method, calcination temperature and time on particle size and physico-chemical features of MgO was studied. The optimal technical conditions were obtained. The XRD and SEM results show that the nanometer MgO prepared under the optimal technical conditions has regular hexagonal lamellar structure, and is composed of nanocrystals with average size between 10 to 25 nm. The existence of dry N2 prevented the sintering of MgO during decomposition processing of Mg(OH)2. Compared with the other nanometer MgO preparation methods, ion exchange resin method has the advantages of low cost, low pollution, high yield and environmental benign; therefore, it appears to be a promising method for the industrial manufacturing of nanometer MgO.
