首次报道了聚乙烯醇缩对甲酰基偶氮氯膦（简称：ＰＶ·ＣＰｐＦ）的合成、纯化及其鉴定方法，并初步探讨了在光度分析和非有机溶剂萃取分离方面的应用。结果表明，小分子显色剂高分子化后，其分析性能有了明显改善，特别是显色灵敏度和萃取率均有不同程度的提高。
For the first time, the synthesis, purification and identification of p-formyl chlorophosphonazo (abbreviation: PV · CPpF) were reported. The application of photometric analysis and non-organic solvent extraction and separation was also discussed. The results showed that after the macromolecularization of small molecule color former, its analytical performance has been significantly improved, especially the color sensitivity and extraction rate have different degrees of improvement.
