flash points of flammable mixtures (Prode Software) 1

[chemlite]

calculating the flash point (StrFLP method , model PRX, BIPs from Prode datatabase) for 80% C8 20% methanol, I get a value (about 273 K) which is below the flash points of pure fluids (stored in Prode database and in agreement with NFPA), is that normal ?
I have no data for this mixture (to verify the result),
thanks for help.

you may find some data in M.S. Thesis of Larson (Flash point Depression in Minimum Boiling Point Azeotropic Mixtures, 1998), the author reports a value of about 1 C (274 K) with seems in good agreement with the value predicted,
hoping this helps,
Marco

you may find (measured) flash points also in DDB
there is a online version (a bit expensive in my opinion)
