is the selection of thermo model that important when estimating flash points for mixtures  with Prode Software ?

For a mixture with water and alcohols I observe large variations selecting NRTL vs. PR

I understand flash points are not estimated by a generic correlation but calculated with a iterative procedure.

[PaoloPemi]

the procedure solves phase equilibria and you can observe different values with different models,

for those liquids I would prefer NRTL over PR, make sure to define BIPs ,

for water-methanol, ethanol etc. these are included in database.

pdender,

you may also find a flash point Depression with azeotropic mixtures as reported in this post
