17.4g (0.05mol) of Hexachlorocyclotriphosphazene and 150ml of toluene were placed in a 250ml three neck flask, the mixture was cooled to about 0 ℃ with an ice brine bath, and ammonia was introduced under it. stir. Filter the reactant for a period of time and air dry the filter cake to obtain a white powdery solid, which is a mixture of aminocyclotriphosphazene and by-product ammonium chloride.
some people also use this method to react with Hexachlorocyclotriphosphazene and monoethanolamine (because I want to react with hydroxyl and other substances, so I choose ethanolamine), triethylamine as acid binder, tetrahydrofuran as solvent, phosphonitrile and ethanolamine are added. When triethylamine is added, solvent and solid are formed immediately. After completion, a large amount of solid is obtained, but after washing with water, it is completely dissolved and no product is distilled out in the solvent. At this time, we can produce a small molecule containing hydroxyl, which is soluble in water. You can also try to extract with ethyl acetate.
it is necessary to carry out relevant operations on the basis of safety during the relevant reaction test of Hexachlorocyclotriphosphazene. Of course, we have understood in detail the steps to be performed and related steps so that we can complete them smoothly.
