Hi, friends of Kel-F,

of course it is unnecessary to use a beaker of water to thaw the
BrF-5. The point is perhaps that, for chemical reasons, it is a
must-not rather than a need-not. As for the distilling, the nice
thing is that you need no certified static temperature or
specific bath, if you cool the Kel-F with a little liquid
nitrogen dynamically, almost teasingly, until the BrF-5 starts to
distill over, and then keep it about the same or just a little
colder. You notice at the end that because of the condensation
the Kel-F has not cooled down all that much.

Yes, hair driers are great for warming it up again. Or a hair
gun?

Summer is coming and the ozone hole seems bigger than ever.

Cheers!
