聚丙烯中新型阻燃剂的综合解析

General Analysis of Novel Flame-Retardant From Polypropylene

采用溶剂提取及梯度洗脱的方法从聚丙烯粒料中分离出一种新型阻燃剂 ,用红外光谱、裂解气相色谱 -质谱、1H和 13 C核磁共振谱以及快原子轰击质谱进行了研究 ,并测定了其元素组成。通过几种方法相互验证 ,确定这种阻燃剂的结构为四溴双酚 S双 ( 2 ,3-二溴丙基 )醚 ,为复杂未知化合物的鉴定提供了有益的借鉴。

A kind of novel flame-retardant is separated from polypropylene through solvent picking-up. The structure of this compound I is confirmed by FTIR, GC/MS, element analysis, 1H NMR and 13C NMR, and so on. Several methods are proofed with one another. This compound I is tetrabromobisphends-bis (2, 3-dibromopropyl) ether, which provides a useful reference to resolution of complicated unknown compounds.
