Freezing Point of Propylene Glycol based Water Solutions

Pure water freezes at 32° F, but a 60% solution of DOWFROST propylene glycol pushes the freezing point down to -60° F. While the freezing point of pure glycol is only -39° F, the synergy between glycol and water results in a much lower freezing point. This is very important for closed-loop systems that may be exposed to freezing conditions.

How Does the Glycol Protect the Loop From Freezing? Pure water freezes at 32° F, but a 60% solution of ethylene glycol pushes the freezing point down to -60° F. While the freezing point of pure glycol is only -39° F, the synergy between glycol and water results in a much lower freezing point.

Freezing-point depression - Wikipedia

Diethylene glycol behaves similarly. The freezing point depression of some mixtures can be explained as a colligative property of solutions but, in highly-concentrated mixtures such as the example, deviations from ideal solution behavior are expected due to the influence of intermolecular forces.

Freezing point as a function of fluid strength. This graph shows how the freezing point can change with fluid strength for several glycol solutions. Note that 100% propylene-glycol does not freeze even in extremely cold conditions. For ethylene (and di-ethylene) glycol, the greatest lowering of freezing point occurs near 70% solution, not 100%.

The effect of adding a solute to a solvent has the opposite effect on the freezing point of a solution as it does on the boiling point. A solution will have a lower freezing point than a pure solvent. The freezing point is the temperature at which the liquid changes to a solid. At a given temperature, if a substance is added to a solvent (such ...
