Hi Kim ‰??

Nope, not necessary. å å å å TFA has covalent C-F bonds; å HF will not be generable under any reasonable lab conditions I can imagine... (I was a synthesis chemist for 22 years & have worked with extensively).å å å å It is a very strong acid, though, & volatile to boot (resp hazard), so you‰??ll want to make sure folks are aware of those hazards...

Hope this helps a bit!
Best regards,
Frank

Subject: [DCHAS-L] Question on trifluoracetic acid & emergencies

One of the labs on campus asked about having an HF emergency kit for trifluoracetic acid use.å

I need the collective wisdom of his group - yes? no? references? (the SDS doesn't mention anything about this)

Thanks
