在含铁有机化合物,尤其是难分解化合物,例如二茂铁衍生物的元素微量分析中,有些文献认为不能同时测定碳、氢和铁。我室采用石英小套管分解样品,用Korbl高锰酸银分解产物作催化剂,在适当的燃烧条件下对含卤、硫、氮的卅多种二茂铁衍生物进行了测定,均得到满意的结果。此法装置简单,操作简便。 1.实验装置如图1 2.分析方法:先将体系通氧气,用电炉4加热催化剂,待CO_2和H_2O吸收管空白值稳定
In the elemental microanalysis of iron-containing organic compounds, especially refractory compounds such as ferrocene derivatives, some documents consider that it is not possible to simultaneously determine carbon, hydrogen and iron. Our chamber used a small quartz tube to decompose the sample, with Korbl permanganate decomposition products as catalyst, under the appropriate conditions of combustion halogen, sulfur, nitrogen, various ferrocene derivatives were measured, are satisfied the result of. This method is simple, easy to operate. 1. The experimental setup is shown in Fig. 1. 2. Analysis method: First, oxygen is passed through the system, and the catalyst is heated with an electric furnace 4 until the blank value of the absorption tube of CO 2 and H 2 O is stable
