制备五氟化磷气体及采用该气体制备六氟磷酸锂的方法
摘要：
五氟化磷气体的制备方法，该方法包括将五氯化磷与无水氟化氢反应，其中，所述反应在溶剂的存在下进行。六氟磷酸锂的制备方法，该方法包括将固体氟化锂与五氟化磷气体接触反应，其中，所述五氟化磷气体为采用本发明的方法制备得到。与现有技术中以五氟化磷气体为原料制备六氟磷酸锂的制备方法相比，本发明提供的制备方法得到的五氟化磷气体的纯度高，成本低廉，采用本发明的方法制备得到的六氟磷酸锂的产率达到93％以上，纯度高达99.95％。
摘要（英）：

A preparation method of phosphorus pentafluoride gas comprises a step of causing phosphorus pentachloride to react with anhydrous hydrogen fluoride, wherein, the reaction occurs in the presence of a solvent. A preparation method of lithium hexaflourophosphate comprises a contact reaction between solid lithium fluoride and phosphorus pentafluoride gas, wherein the phosphorus pentafluoride gas is prepared by the method of the invention. Compared with the preparation method of the lithium hexaflourophosphate with the phosphorus pentafluoride gas as the raw material in the prior art, the phosphorus pentafluoride gas prepared by the preparation method of the invention has higher purity and lower cost. The yield of the lithium hexaflourophosphate prepared by the method of the invention is higher than 93%, and the purity thereof is up to 99.95%.
