first, store under argon and put it in the freezer.
Second, I am not quite sure the purifiaction method. For triflic anhydride,
you can distill it. (High toxic vapor)
By the way, it is very easy to liberate SO2 and produce a viscous liquid.
So, buy fresh triflic acid; use it in the glove box; store it under Argon.
Good Luck!

Subject: ORGLIST: how to store and purify Trifluoromethanesulfonic acid?
Date: Wed, 10 Jan 2007 11:40:14 -0500
Hi, everyone, I have a question about how to store and purify
trifluoromethanesulfonic acid. Trifluoromethanesulfonic acid(+AD4-98+ACU-)is
apt to turn to yellow solution after the bottle is open. Any suggestion will
be appreciated.
Thank you
