A process for fluorination of borohydride salts including providing a reaction medium comprising HF and a superacid. A borohydride salt compound is added to the reaction medium. The borohydride salt is reacted with the reaction medium under conditions to form a fluorinated borohydride salt. In addition, reactor vessels may be provided for reacting the HF, superacid additive and borohydride that are fabricated from materials resistant to superacid compositions.
