Uses

Used in Flame Retardants Industry:
Hexamethoxyphosphazine is used as a flame retardant for polyurethane foams. It is incorporated into the foam during the manufacturing process, providing enhanced fire resistance and reducing the risk of ignition. HMPZ works by releasing non-flammable gases and forming a protective char layer on the surface of the material, which helps to slow down the spread of flames and limit heat transfer.
Used in Lithium-ion Batteries Industry:
Hexamethoxyphosphazine is also used as an additive in lithium-ion batteries. It is added to the electrolyte solution to improve the performance and safety of the battery. HMPZ acts as a stabilizer, reducing the formation of unwanted side products and improving the overall efficiency of the battery. Additionally, it can help to prevent the growth of dendrites, which can cause short circuits and lead to battery failure.

Phosphazene compound, composite containing phosphazene compound, flame retardant containing composite and application

The invention relates to a phosphazene compound, a composite containing the phosphazene compound, a flame retardant containing the composite and application. The crystal form of the cyclotriphosphazene derivative flame retardant synthesized by using the method is most stable, and the cyclotriphosphazene derivative flame retardant is high in heat stability and high in flame retardant efficiency; moreover, when the crystal type cyclotriphosphazene derivative flame retardant synthesized by using the method is added into a material, such as engineering plastics, general-purpose plastics, a lithiumion battery electrolyte, a flame retardant fabric and flame retardant paper, a high flame retardant performance is achieved, the crystal form is stable, the flame retardant is resistant to drip, onlyan extremely small adding amount is needed, the flame retardant performance of the material can reach the V-0 standards, and other properties of the material are little affected.

Studies of Phosphazenes Part: 24 - Cyclophosphazenecarboxylate Derivatives and Their Use in Synthesis of Amides

Penta(methoxy)(hydroxy)cyclotriphosphazene, N3P3(OMe)5(OH) (1), reacts with acetyl and benzoyl chlorides in the presence of triethylamine to yield the phosphazene-carboxylate derivatives, N3P3(OMe)5(OCOR) , as shown by IR and PMR spectroscopic data.Compounds 2 and 3 react with primary amines to afford amides in 85percent yield.

Studies of Phosphazenes. Part 13. Thermal Rearrangement Reactions of Some Methoxycyclophosphazenes

The methoxycyclophosphazenes n (n = 3-6) rearrange on heating to give oxocyclophosphazanes, n.Isomeric products are formed when n = 4-6.The 1H, 31P, and 13C n.m.r. data for the starting materials and the products are presented.The ethoxy- and n-propoxy-derivatives N3P3(OR)6 do not undergo the above rearrangement.The geminal derivatives N3P3R2(OMe)4 (R = Ph or NHBut) on heating yield both fully and partially rearranged products, namely dioxaphosphaz-1-enes and oxophosphazadienes, as shown by 270-MHz 1H n.m.r. spectroscopy.The non-geminal derivative N3P3(NMe2)2(OMe)4 gives only the fully rearranged product N3Me3P3(NMe2)2O3(OMe), whose structure has been established from its 1H and 31P n.m.r. spectra.
