一种新型无卤阻燃剂的合成研究

Studies on Synthesis of A New-type Nonhalogen Fire-retardant

通过三氟氧磷与对苯二胺在-50℃反应,合成了新型的膨胀型阻燃剂磷酰三(4-氨基苯基)胺,产率95%,熔点198.8-200.6℃。阻燃对比试验表明,该产物具有较为理想的阻燃效果,经改进后可望成为有实用价值的新型膨胀型阻燃剂。

A new- type fire - retardant, phosphoryl tri （4 - aminophenyl） amide, was synthesized by the reaction of phosphoryl trichloride with para-phenylene diamine, its yield is 95% and melting point is 198. 8-200. 6℃. The contrast fire-retarding test shows that the product has ideal retarding effect, and we can sure it can become a new-type and practical intumescent flame retardant after improved.
