一种含醚键DOPO类似物的制备方法
摘要：
本发明提供一种含醚键DOPO类似物有机磷阻然剂的制备方法，以DOPO和二甘醇(DEG)为反应原料，在杂多酸催化剂催化下反应，能够保持高纯度的同时提高反应收率，有利于工业化生产。
摘要（英）：

The invention provides a preparation method of an ether-containing bond DOPO analogue organophosphorus flame retardant. DOPO and diethylene glycol (DEG) serving as reaction raw materials are reacted under the catalysis of a heteropolyacid catalyst; the reaction yield can be increased while high purity can be maintained; and industrialized production is benefited.
