六甲基磷酰三胺(简称六磷胺)是一种典型的对质子隋性的高沸点有机极性溶剂。它作为溶剂触媒及各种助剂而广泛应用于有机合成、高分子材料、农药、医药、国防等许多领域。我所聚苯硫醚工程塑料采用六磷胺为缩聚溶剂,需对溶剂的纯度以及酒精萃取回收六磷胺中的六磷胺,对二氯苯进行分析测定。因而需要一种快速、准确的分析方法,以满足试验研究与生产的要求。
Hexamethylphosphoric triamide (referred to as hexafluorophosphate) is a typical proton-inert high boiling point organic polar solvents. As a solvent catalyst and various additives, it is widely used in many fields such as organic synthesis, polymer materials, pesticides, medicine, national defense and so on. I polyphenylene sulfide engineering plastics using hexametaphosphate as a polycondensation solvent, the purity of the solvent and the need to extract the hexamine phosphate hexamine, p-dichlorobenzene analysis and determination. There is a need for a fast and accurate analytical method to meet the requirements of experimental research and production.
