Glycerine - Boiling and Freezing Points

Calculator for boiling and freezing points of glycerine (glycerin/glycerol) aqueous solutions. The boiling points decrease with increased glycerine concentration, while freezing points decrease until 66.7% glycerine concentration, then increase above that threshold.

Glycerine Solution Properties

This calculator determines the boiling and freezing points of glycerine-water mixtures based on concentration.

Key Facts:

Boiling points decrease with increased glycerine concentration
Freezing points decrease until glycerine concentration reaches 66.7% (mass)
Above 66.7% glycerine, freezing points begin to increase
All data measured at 60°F (15.6°C) reference temperature for specific gravity
