Does glycol elevate or depress the boiling point of water? The makers of automotive antifreeze make clear claims as to the freezing point depression, but don't specifically say the BP is elevated. A simple test that I did, seemed to indicate that the BP is actually depressed at low concentrations. The CRC Handbook has vapor pressures or all sorts of compounds as does Merk Index. It also gives equations and constants for BP elevation for salts dissolved in various solvents, but nowhere can I find the vapor pressure of gylcol/water mixtures (BP is temp where vapor pressure = one atm).
