enthalpy of propylene glycol

[pashko]

Hello all,
I have been looking for enthalpy (Btu/lb) or internal energy (Btu/lb) tables of propylene glycol (or propylene glycol/water solution) and can't find.
Does anybody know where to find this info.
I would really appreciate that.
Thanks.

I think it will be easier to find specific heat data at various temperatures, curve fit the data to a polynomial (CP = A + BT + CT2 + . . . ), and utilize thermodynamics ( [∫]dH = [∫]Cp dT) to get what you want.

Good luck,
