六氟丙烯三聚物制备研究

Preparation of hexafluoropropene trimers

六氟丙烯可通过气相和液相法进行聚合制得六氟丙烯三聚物,即全氟壬烯,全氟壬烯可以进一步衍生出如全氟壬烯氧基苯磺酸钠等多种氟碳表面活性剂,是一种比较有用的含氟产品。主要对六氟丙烯聚合的方式气相法和液相法进行了比较,其中液相法的使用较多;而且对国内在六氟丙烯三聚研究方面的进展情况进行了介绍和对比。六氟丙烯三聚体和其衍生物主要被用在氟碳表面活性剂领域,有较好的发展前景。

As a useful fluorinated product, hexafluoropropene trimers （perfluorinated nonelae） can be prepared from hexafluoropropene oligomerization by gas phase - and liquid phase - methods, and many fluorocarbon surfactants such as full -fluoride nonene oxygen benzene sodium can be derived from perfluorinated nonene. Gas phase and liquid phase were compared and the latter phase is more common. And then, the research advance in hexafluoropropene trimer at home was in- troduced and compared. Hexafluoropropene and its derivatives are mainly used in the field of fluorocarbon surfactantve and have a better forground.
