Method for detecting concentration of ammonium persulfate in ethyl alcohol-chloroform mixed solution

Acidichromism is a color change form developed quickly in recent years. Even if many researches of a polymer acidichromism performance exist, and a relationship between an acidichromism performance and a solvent and a relationship between an acidichromism performance and acid strength are already reported, a method for detecting acid concentration in a mixed solution by utilizing the acidichromismperformance of a monomer is not reported yet, therefore, according to the invention, EDOT and 2-amidogen-4,6-diiodopyrimidine2-aminopyrimidine are adopted as raw materials to synthesize an APE monomer, a structural characterization and performance research is carried out on the monomer, and a method for detecting concentration of ammonium persulfate in an ethyl alcohol-chloroform mixed solution is developed. 酸致变色是近几年来发展较快的种变色形式.虽然聚合物酸致变色性能方面的研究较多，酸致变色性能与溶剂之间的关系和酸致变色性能与酸强度之间的关系已有报道，但是利用单体的酸致变色性能检测混合溶液中的酸浓度尚未报道.因此在本发明，以EDOT和 2-氨基-4,6-二碘嘧啶2-氨基嘧啶为原料合成了APE单体.对单体进行了结构表征和性能研究并开发了种在乙醇-氯仿混合溶液中过硫酸铵浓度的检测方法。
