Abstract The xanthato complexes of zirconyl(IV) ZrO(S 2 COR) 2 · 2H 2 O (R = CH 3 , C 2 H 5 or C 3 H 7 ) were prepared in aqueous medium and characterized by elemental analysis, conductance. magnetic susceptibility measurements and infrared spectral data. The thermal behaviour of these compounds under non-isothermal conditions was investigated by thermogravimetric. derivative thermogravimetric and
摘要 在水性介质中制备了氧化锆(IV) ZrO(S 2 COR) 2 · 2H 2 O (R = CH 3 、C 2 H 5 或C 3 H 7 )的黄原配合物,并通过元素分析和电导表征。磁化率测量和红外光谱数据。通过热重分析研究了这些化合物在非等温条件下的热行为。在空气和 N 2 气氛中的衍生热重和差示扫描量热技术。观察到配合物的热稳定性随着黄原酸酯部分末端 R 基团链长的增加而增加,动力学参数如表观活化能和反应顺序由 Coats 和 Redfern 的图形方法确定。从 DSC 曲线计算分解步骤的反应热。
