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,
Try this one: http://www.vngas.com/pdf/g143.pdf
although you'd proabably get that if the air was dry enough.
How dry will the air be at the burning cherry on a cigarette? Reese
