A laboratory-scale synthesis of high-purity AsF5 by direct fluorination of AsF3

Arsenic pentafluoride has found extensive use as a fluoride ion acceptor and oxidant in the field of synthetic inorganic fluorine chemistry. A detailed, laboratory-scale synthesis of high-purity, HF-free AsF5 from AsF3 and F2 gas at low temperatures under static conditions is described. The detailed synthesis of HF-free AsF3 is also described.
