Two pathways to obtaining deuterium fluoride in the system D-2-AgF2-CIF3 th
at exclude direct con-tact of D-2 with CIF3 are investigated: (1) DF synthe
sis by the action of D-2 on AgF2 and AgF2 regeneration by the action of CIF
3 on Ag and (2) a three-stage synthesis simultaneously producing two deuter
ium halides (DF + DC1). The two-stage process is recommended as a convenien
t route to obtain DF of high chemical and isotopic (99% D) purity on a labo
ratory scale from commercially available reagents.
