草酸钛(Ⅳ)配合物的合成和热性质研究

Studies on the Synthesis and Thermal Decomposition Reactions of Titanium (Ⅳ) Oxalate

合成了新配合物Ti_2O_2(OH)_2C_2O_4·3H_2O,利用元素分析,化学分析、热重和红外光谱确定了其组成。热重和差热扫描量热法研究了它在空气下的热分解特性,计算机求解配合物在空气条件下脱水阶段的反应级数n和活化能E_a,在550℃灼烧1小时,可得锐钛型TiO_3。

Compornd of Ti_2O_2 (OH)_2C_2O_1·3H_2O was synthesized and its composition was ascertained by element analysis, TG/DSC and IR. It was not yet reported. The thermal decomposition reaction of titanium (Ⅳ) oxalate in air was Studied. The complex remove water at 40～206℃ and having 2.0 of reaction order and 50. 2KJ mol^(-1) of the decomposition activation energy pure anatase TiO_2 was abtained by heating the complex at 550℃ for l hour.
