用重量法、容量法和放射性示踪法测定了氯化铯和三氯化锑在冰醋酸介质中形成的复盐的组成,初步确定为7CsCl·5SbCl_3。并且发现该复盐在一定条件下,经过适当时间可能逐渐向4CsCl·3SbCl_3转变,而不是向3CsCl·2SBCl_3转变.研究了两种复盐7CsCl·5SbCl_3和3CsCl_3·2SbCl_3在冰醋酸和9.965N盐酸中的溶解动力学,分別绘出它们的溶解动力学曲线。结果指出,除了3CsCl·2SbCl_3复盐在9.965N盐酸中是稳定的外,7CsCl·5SBCl_3复盐在冰醋酸和9.965N盐酸中以及3CsCl·2SbCl_3复盐在冰醋酸中均不稳定。也作了7CsCl·5SBCl_3和3CsCl·2SbCl_3两种复盐的初步热重分析和显微结晶观察,绘出了热重分析曲线,并计算了两个大平台部分的残重百分数。这些结果也指出两种复盐显然不同。
The composition of double salt formed by cesium chloride and antimony trichloride in glacial acetic acid medium was determined by gravimetric method, volumetric method and radioactive tracer method. The initial concentration of 7CsCl · 5SbCl_3 was determined. And it was found that under certain conditions, the complex salt may gradually shift to 4CsCl · 3SbCl_3 rather than to 3CsCl · 2SBCl_3 under appropriate conditions.Studies on the effect of two kinds of double salts 7CsCl · 5SbCl_3 and 3CsCl_3 · 2SbCl_3 in glacial acetic acid and 9.965N hydrochloric acid The dissolution kinetics, respectively, draw their dissolution kinetic curves. The results indicate that, except that the complex salt of 3 CsCl · 2SbCl_3 is stable in 9.965N hydrochloric acid, the double salts of 7CsCl · 5SBCl_3 are unstable in both glacial acetic acid and 9.965N hydrochloric acid and 3CsCl · 2SbCl_3 double salts in glacial acetic acid. The thermogravimetric analysis and microscopic observation of two kinds of double salts of 7 CsCl · 5SBCl 3 and 3 CsCl · 2SbCl 3 were also made. The thermogravimetric analysis curves were drawn and the percentages of residual weight of the two large platforms were calculated. These results also indicate that the two double salts are obviously different.
