Need help with finding a boiling point

I didn't want to limit this question to the solar tab even though this question is solar based.
If I have a closed loop solar thermal system that is pressurized to 60psi, and is a 50% propylene glycol solution, how do I find the boiling point of that fluid?
I am trying to find out how to structure the math equation. I am fairly certain that I need the specific gravity and/or specific heat of the 50% PG solution as well as the 60psi, but have no idea how to formulate these into a usable and correct math equation.

Water would have a boiling point of 307 degrees at 60 psig, and the glycol would add somewhat to this. Propylene glycol at 50% only adds 10 degrees to the boiling point, so an answer would be 317 degrees at that pressure to be safe.0
