新型锂镁分离有机膦树脂的合成

The Synthesis of the New Organic Phosphine Resin for Separating Lithium and Magnesium

以线性酚醛树脂为母体,其经溴甲基化、三乙氧基磷亲核取代及Arbuzov重排反应,合成一种新型有机膦树脂。该树脂经红外表征。通过Gauss软件对产物结构单元类似物进行频率计算,得到其理论计算红外图谱,与产物实测红外图谱进行比对,表明对酚醛树脂高分子骨架上官能团改造是成功的,合成了一种新型的有机膦树脂。

Based on the linear phenolic resin, through bromomethylated, triethoxyphosphine nucleophilic substitution and Arbuzov rearrangement reaction, a new organic phosphine resin was synthesized. The resin was characterized by IR. In addition, the frequency of structural units analogues of product was calculated using Gauss software, and the resulting theoretical calculation of infrared spectrum was compared with the measured infrared spectrum. It indicated that the transformation of backbone functional groups on the phenolic resin polymer was successful and the new type of organic phosphine resin was synthesized.
