摘要
本文首次报告了用热重—差热(TG～DTA)联合研究了三草酸基合铬(Ⅲ)酸钾的固相合成及在空气气氛中的热分解过程。测定了合成产物和热分解后固相物质的电子光谱,实验结果表明:K_3[Cr(C_2O_4)_3]的固相合成和热分解均是氧化还原反应。结果准确,方法可靠。
This paper first reports the solid phase synthesis of trioxalatochro-miate potassium by using the differential thermal-thermogravimetry analysis (TG-DTA)and its pyrolysis processes in the air. The electronic spectrums of the synthetic products and the solid phase substances after pyrolysis have also been determined.The results of the experiments indicate that the solid phase synthesis of K3[Cr(C2O4)3]and the pyrolysis are both oxidation-reduction reactions. The results are accurate and the method is reliable.
