Freezing Point - Best Mixture

[AaronC]

Well, I found some info on this and I thought I would share:

Methanol \ Water Mixtures

Methanol Conc.
Wt. % (Vol.%)---Freezing Point,F(C)---Flash Point, (TCC) F(C)
0(0)--------------- 32(0)--------------- No Flash
10(13)----------- 20(-7)-------------- 130(54)
20(24)----------- 0(-18)-------------- 110(43)
30(35)------------ -15(-26)------------ 95(35)
