乙氧基镁的合成,是用四氯化碳为催化剂。为了控制系统中有机氯的含量(四氯化碳在固体中的含量,总氯的含量不大于0.1%),以保证产品质量,所以测定乙氧基镁中微量有机氯含量是必要的。根据工作需要,我们采用色谱法对乙氧基镁中微量四氯化碳含量进行了测定。方法介绍如下: Synthesis of magnesium oxychloride is the use of carbon tetrachloride as a catalyst. In order to control the content of organochlorine in the system (the content of CTC in solid, the content of total chlorine is not more than 0.1%), in order to guarantee the product quality, it is necessary to determine trace organochlorine in ethoxymagnesium. According to the needs of the work, we use the chromatographic method to determine the content of trace carbon tetrachloride in magnesium oxychloride. The method is introduced as follows:
