All of the syntheses seem to use argon. Do you know if you can use nitrogen as the inert gas in making potassium graphite? Thanks, Martin

Hi Martin,

In my postdoc lab, students made it under vacuum using a sealabe vessel if I remember correctly. Maybe under N2 or argon. Be sure to use a glass-coated stirbar.

Also, many many small fires have been caused by quenching the vessel you make the KC8 in. Its spontanously flammable in air. Be very careful. 

I have purposefully avoided it in my current research even though it would be great to get crystal structures of reduced species. I just don't want to risk it.

Hi Kyle,

Thanks for the insight. 

I will be very careful if I do try to make and use it. Small scale reactions, and I probalby will quench the material in the glovebox with 50:50 iPrOH:t-butanol, then purge the box out to remove the alcohol vapors.

Thanks again,
