Abstract:
Arsenic can be an impurity in phosphorous pentafluoride production processes. It is desirable to remove arsenic from phosphorous pentafluoride prior to using of the phosphorous pentafluoride in the production of lithium hexafluorophosphate. The present technology provides methods of removing arsenic from phosphorous pentafluoride by extractive distillation.
