以过硫酸铵为氧化剂,采用紫外光谱原位跟踪的方法对N-乙基苯胺在1.0mol/L的HCl溶液中的化学氧化聚合进行了动力学的研究。研究结果表明,聚合过程中,体系呈均相且颜色随聚合时间的延长而加深。中间产物和聚合物分别对应的吸收峰的强度也随EA和APS的浓度而变化。通过计算推导出了N-乙基苯胺的聚合速率与EA和APS的浓度的关系式。
The oxidative polymerization of N-ethylaniline in 1.0 mol / L HCl solution was studied by ammonium persulfate as oxidant and in-situ UV tracking. The results show that the polymerization process, the system was homogeneous and the color with the extension of polymerization time and deepen. The intensity of the absorption peak corresponding to the intermediate product and the polymer, respectively, also varies depending on the concentrations of EA and APS. The relationship between the polymerization rate of N-ethylaniline and the concentration of EA and APS was deduced by calculation.
