Hexafluorobenzene
Hexafluorobenzene
(OP)
I am stuck on my design project until I find out the internal pressure of 4cc of Hexafluorobenzene inside a small ampoule at 250C. I am willing to pay for someone to work with me on that and other tracer materials.

You may use this or similar sources for vap press for other chemicals.

I'd be wary of using the SRK or virial equation to derive this pressure, given its structure. Will write back if I find something that will help.

But first, you'll have to determine if this ampoule will indeed go into dense phase ( Pr >1.0). The NIST link should help with calculating Zc for this - since this is a student posting (?), you'll have to figure this out yourself.
