摘要
本文以季戊四醇、三氯化磷、环氧丙烷和氯气为原料，通过优化工艺条件，合成了新型高效阻燃剂。采用红外、核磁磷谱、飞渡质谱等分析方法鉴定了产品结构，并测试了产品应用于ＰＶＣ难燃输送带中的阻燃性能。
The novel and highly effective fire retardant is synthesized from pentaerythritol,phosphoric trichloride,propene oxide and chlorine,and its structure is identified with IR,31P NMR,flying MS,the property of the product which is used in fire-proof conveyor belt is detected.
