'''氟磷酸'''是一种[[无机化合物]]，化学式 H<sub>2</sub>PO<sub>3</sub>F。它是一种无色液体。

== 制备==
氟磷酸可以由[[五氧化二磷]]和[[氢氟酸]]反应而成。纯度较低的氟磷酸也可以由[[三氟氧磷]]的[[水解]]而成，会先形成二氟磷酸：<ref>Charles B. Lindahl, Tariq Mahmood (2000): ''Fluorine Compounds, Inorganic, Phosphorus''. Kirk‐Othmer Encyclopedia of Chemical Technology. [[doi:10.1002/0471238961.1608151912091404.a01]]. ISBN 9780471484943.</ref>

<chem>POF3 + H2O -> HPO2F2 + HF</chem>

二氟磷酸继续水解成氟磷酸：

<chem>HPO2F2 + H2O -> H2PO3F +  HF</chem> 

== 性质==
氟磷酸是一种无色液体，和水混溶。<ref name="GESTIS" />

== 用处==
氟磷酸可用于{{le|零件清洗|Parts_cleaning}}，也是一种[[抛光]]剂和[[催化剂]]。<ref>{{Internetquelle |autor= |url=https://cameochemicals.noaa.gov/chemical/3988 |titel=Chemical Datasheet – FLUOROPHOSPHORIC ACID, ANHYDROUS |hrsg=Cameo Chemicals |abruf=2021-05-04 }} {{Wayback|url=https://cameochemicals.noaa.gov/chemical/3988 |date=20210608202345 }} {{Cite web |url=https://cameochemicals.noaa.gov/chemical/3988 |title=存档副本 |access-date=2021-07-12 |archive-date=2021-06-08 |archive-url=https://web.archive.org/web/20210608202345/https://cameochemicals.noaa.gov/chemical/3988 |dead-url=unfit }}</ref>
