| Abstract: The title compounds:Ti(OH)(C4H4O5)·1.5H2O, Ti(OH)(C4H4O6)·1.5H2O and Ti(C6H5O7)·1.5H2O were synthesized by the reaction of titanium trichloride with ammonium malate, ammonium tartrate, ammonium citrate respectively. The composition of these products was determined by the methods of chemical, elemental analyses. Its coordination structure was assigned on the basis of magnetic susceptibility, IR and X-ray diffraction. They were not yet reported. The thermal decomposition reaction of titanium(Ⅲ) hydrocarboxylate in air were studied. The activity energy Ea,enthalpy chanqe ΔrH and entropy change ΔrS were determined from TG and DSC curves. |
