四氟硼锂和六氟砷锂的合成与拉曼光谱分析

Preparation and Raman spectral analysis of lithium tetrafluoroborate and lithium hexafluoroarsenate

介绍了合成高纯无水的ＬｉＢＦ＿４和ＬＩＡｓＦ＿６的新方法，并讨论了其合成条件，指出制备多孔状ＬｉＦ和控制反应温度是合成的关键。拉曼光谱分析表明，ＬｉＢＦ＿４产品同进口标准样品基本一致，在同样条件下制备的ＬｉＡＳＦ＿６的拉曼谱同文献值一样。

The methods and optimum conditions for thepreparation of LiBF4 and LiAsF6 of high purity werestudied, and it was found that the preparation ofporous, highly reactive LiF and the reaction temperature were the main keys to high yields of the products.From the comparison of the Raman spectrum of theLiBF4 synthesized with that of exotic reference material it was found that the LiBF4 had the same quality.The Raman spectrum of the LiAsF6 produced underthe same conditions is in agreement with that in theliterature.
