有机锗化合物中碳氢的快速测定

RAPID DETERMINATION OF CARBON AND HYDROGEN IN ORGANOGERMANIUM COMPOUNDS

报道了用Co3O4 作覆盖氧化剂分析有机锗化合物中碳氢元素的方法。通过对 9个样品的十几次分析 ,碳、氢的相对误差分别小于± 1.30 % ,4 .4 0 %。方法简便 ,结果稳定可靠 ,可用于含锗有机化合物的碳氢分析。

An oxide of cobalt (Co 3O 4) was prepared and used as an oxidizing agent in the determination of hydrogen and carbon by the combustion method using UM 3B microanalyzer for elementary organic analysis. From the results obtained by the analysis of 13 samples from nine batches in the preparation of a same organogermanium compound, it was found that values of relative errors of less than ±5.1% for hydrogen and of less than ±1.3% for carbon were obtained. The method was simple and convenient. Reproducible and accurate results were obtained.
