| 摘 要： | 研究了全氟正丙基乙烯基醚(以下简称"PPVE")萃取提纯方法。使用了多种萃取剂对含有CF3CF2CF2OCFHCF3(以下简称"含氢醚")的PPVE进行了萃取性能的比较,通过选择性系数对比,确认无水乙醇为最优萃取剂。并使用无水乙醇对含有含氢醚的PPVE进行了多级提纯,使PPVE的含量达到99.0%以上。

| Abstract: | This paper studies the perfluoropropylvinyl ether extraction purification method. Various extraction solvent to extract CF3 CF2 CF2OCFHCF3 -PPVE mixture are compared, and the extraction performance through se-lective coefficient of contrast, anhydrous ethanol identified as optimal extraction agent. Through multi - stage purifi-cation by using anhydrous ethanol on CF3CF2CF2OCFHCF3-PPVE mixture, we make the main content of perflu- oropropylvinyl ether above 99.0%. |
