• A Novel Reaction Medium: Perfluorocarbon Fluids
  作者：Dong-Wei Zhu

  DOI：10.1055/s-1993-25975

  日期：——

  The use of perfluorocarbon (PFC) fluids such as perfluorinated alkanes and alkylamines as inert medium for organic reactions is demonstrated with advantages summarized. PFC fluids have been found to be very useful in organic reactions where a medium is needed for refluxing and for separating a low boiling component, or where an extremely nonpolar/inert medium is required for reactions carried out under vigorous conditions. The PFC fluids are not miscible with most organic compounds and therefore offer good separatory properties that common organic solvents do not have.

  全氟碳化物（PFC）流体（如全氟烷烃和烷基胺）作为惰性介质用于有机反应，其优点已得到证实和总结。在需要介质进行回流和分离低沸点成分的有机反应中，或者在剧烈条件下进行的反应中需要极度非极性/惰性介质时，PFC 流体非常有用。PFC 溶剂不与大多数有机化合物混溶，因此具有普通有机溶剂所不具备的良好分离特性。
