摘要
顺—反异构体的研究,在配合物化学中占有重要的地位。二水二草酸合铬酸钾这一配合物顺、反异构体的制备和异构化现象的研究已有报导,但多限于水溶液体系。也有关于该配合物热稳定性和热分解动力学研究的报导但对固相中该配合物异构体转变的研究尚未见报导。本文利用DTA方法,对二水二草酸合铬酸钾顺。
The isomerization betweem cis- and trans- K[Cr(C2O4)2·(H2O)2] has been studied using differential thermal analysis. The transformation of the isomerization between cis- and trans-complexes has been carried out up to 230℃ in an atmosphere of air. The heat of the transformation is -102kJ·mor-1.
