一、前言在我校试生产新型的人工降雨催化剂——四聚乙醛的过程中,原来只根据聚合反应的温度变化来确定反应的终点,一般反应周期为8小时左右.为了进一步探索乙醛聚合过程的反应动态,以便确定反应的终点,我们用国产102G气相色谱仪的氢火焰离子化捡测器部分进行了四聚乙醛试生产过程的反应动态分析,发现从加酸催化反应开始三小时后,反应液的各种组分已基本上处于相对稳定的状态,同时对色谱流出曲线中的一个未知的拖尾峰的出现和消失进行了初步的探讨,为缩短反应周期提供了初步的数据.
I. Introduction In my trial to produce a new type of artificial rainfall catalyst - the process of the four, the original only based on polymerization reaction temperature to determine the end of the reaction, the general reaction period of about 8 hours.In order to further explore the acetaldehyde Polymerization reaction to determine the end of the reaction, we use domestic hydrogen peroxide flame ionization 102G GC detector part of the trial production of tetraacetic acid reaction dynamic analysis and found that from the acid-catalyzed reaction began three After hours, the various components of the reaction solution have basically been in a relatively stable state, and at the same time, the appearance and disappearance of an unknown tailing peak in the chromatographic outflow curve have been discussed preliminarily, providing preliminary preliminary results for shortening the reaction period data.
