I would bet that there is SOMETHING that is dissolved by liquid freon. Just mark your letters with the stuff and look for the integrity of the mark at the other end.
Or... is there something that REACTS to freon in an interesting way...?

I think freon is incredibly inert, that's why it's used.
Heat freon up enough, it turns into phosgene gas (as it breaks down into simpler components). The CBR types call that Blood Agent. Just think of how carbon monoxide supplants oxygen in your red blood cells, that's what phosgene gas does. I do not seem to remember the critical temperature but a lit cigarette will do it.

Here's a link to the MSDS http://www.ansul.com/Material_Safety_Data_Sheets/F-85312.pdf it says above 900 F Freon will decompose into hydrochloric and hydrofluoric acids. Doesn't mention phosgene, although you'd proabably get that if the air was dry enough. George George
