enthalpy of propylene glycol

enthalpy of propylene glycol

(OP)
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.

RE: enthalpy of propylene glycol

Dow has some properties: http://www.dow.com/polyglycols/ppgc/na/products/pp...
NIST might have more (see thread391-230059: what is the value of overall heat transfer coeffient of water - glycol for link)

Another link that might be helpful is thread391-155955: Ethylene Glycol vs Propylene Glycol

RE: enthalpy of propylene glycol

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,

Technically, the glass is always full - 1/2 air and 1/2 water.
