Things You Will Need
If the freezing point of the material you wish to separate from the water is lower than 32-degrees Fahrenheit, you can let your freezer do the distilling for you. Acetic acid (vinegar) has a significantly lower freezing point than water and is an ideal home project for freeze distillation.
-
Pour the mother of vinegar into a 2-liter bottle. Leave at least three inches of airspace at the top of the bottle to allow the water to expand as it freezes.
-
Place the bottle into your freezer.
-
Allow the bottle to freeze for at least 24 hours.
-
Remove the bottle from the freezer and remove the cap.
-
Place a funnel into the mouth of an empty bottle. Place the frozen bottle neck down into the funnel.
-
Allow the liquid from the frozen bottle to drain until the ice inside it is clear.
-
Discard the ice remaining in the frozen bottle.
