CN101993456A 一种磷杂菲磷腈无卤阻燃剂的制备方法 失效 - 权利终止

一种磷杂菲磷腈无卤阻燃剂的制备方法
摘要：
本发明涉及一种基于磷杂菲磷腈无卤阻燃剂六-(磷杂菲-羟甲基-苯氧基)-环三磷腈的制备方法。六-(磷杂菲-羟甲基-苯氧基)-环三磷腈的结构式见附图1。通过采用六(4-醛基-苯氧基)-环三磷腈与化合物9，10-二氢-9-氧杂-10-磷杂菲-10-氧化物(DOPO)进行熔融加成反应的方式制备六-(磷杂菲-羟甲基-苯氧基)-环三磷腈，并采用有机溶剂洗涤法进行了提纯，获得了高纯度、高收率的六-(磷杂菲-羟甲基-苯氧基)-环三磷腈白色粉末。
摘要（英）：

The invention relates to a method for preparing a phosphaphenanthrene and phosphazene halogen-free retardant agent hexa-(phosphaphenanthrene-hydroxymethyl-phenoxyl)-cyclotriphosphazene. The structural formula of the hexa-(phosphaphenanthrene-hydroxymethyl-phenoxyl)-cyclotriphosphazene is shown in a figure 1. The hexa-(phosphaphenanthrene-hydroxymethyl-phenoxyl)-cyclotriphosphazene is prepared through a fusion addition reaction on hexa(4-formyl-phenoxyl)-cyclotriphosphazene and a compound of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO), and is purified by adopting an organic solvenet washing method to obtain the white powder of the hexa-(phosphaphenanthrene-hydroxymethyl-phenoxyl)-cyclotriphosphazene with high purity and high yield.
