The result indicated that: the amount of the excess HF formed direct ratio to the yield of phosphorus pentafluoride and the optimum amount of the excess HF used is about 35%; the trickling rate of oleum shouldnt make the temperature of hexafluorophosphoric acid exceed 25 ℃ and the amount of oleum is 110% to 125% that of stoichiometry so that the content of phosphorus pentafluoride can be achieved 90%; the time and temperature of heating hexafluorophosphoric acid influenced both the yield and the content of phosphorus pentafluoride, and the optimum time should be about 30 minutes and the proper temperature was 148 to 153℃; when alcohol used asrefrigerant, the content of phosphorus pentafluoride was 94.03%, and the content can be up to 97.38%, provided that using liquid nitrogen as refrigerant.

通过实验发现，氟化氢用量与五氟化磷的产率成正比，最佳过量百分率宜在35％左右；发烟硫酸的滴加速度不能使中间产物温度大于25℃，发烟硫酸用量大于理论量10％～25％时，得到的五氟化磷纯度高于90％；六氟磷酸的加热温度对五氟化磷的产率和纯度均有影响，宜在148～153℃的范围内，加热时间应在30分钟左右；用工业酒精做冷凝介质得到的五氟化磷纯度最高只能到达94.03％，使用液氮做冷凝介质可以使五氟化磷的纯度达97.38％以上。
