Technology Process of Krypton difluoride

There total 8 articles about Krypton difluoride which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:
Guidance literature:
In neat (no solvent); electrical discharge at -183 to - 196°C and 20 Torr pressure; typical conditions: F2-Kr-mixture (1.1:1) at 20 Torr and -196°C, electrical discharge of 20 mA and 3000-4000 V;; at typical conditions, 0.25g KrF2/h are obtained; sublimation of raw product below 0°C; careful drying in a pre-fluorinated apparatus;;
