freezing temp of mixtures of isopropyl alcohol and water 1

ivymike · Mar 6, 2002

Does anyone have a good online source that I could refer to for the freezing temperature (at 1 atm) of various concentrations of isopropyl alcohol in water? If there isn't an online source, I'd appreciate it if someone could post whatever info he/she might have.

Thanks in advance,
Isaac

20 7.6 8.5
24 9.1 10.9
28 10.2
32 10.7

Don't ask me why the table stops where it does, I guess the solution separates into two liquid phases, but I don't know.

This is from the CRC handbook to Chemistry and Physics, so the wiggles in the curves should be authoritative.
