Acetic acid from vinegar. A better method, Hive .

You could destill acetic acid, but you would need a stronger vinegar than 5%, because there is an azeotrope betwen water and 3% acetic acid. I use 30% vinegar essence and destill trough an vigereux column at a veeeery slow rate.. the destillate came over at 100 C and smells acetic.

Fractional Freezing / Freeze Distillation - General .

I was looking at a rotovap. I wonder if one might use that and a chiller to freeze the liquid onto the walls at room temp as it rotated in a super chilled liquid. Then when enough has be frozen, start pulling a vacuum to remove the more volatile liquids and dump the liquid out leaving the acetic acid. Kind of a reverse use for the Rotovap.

Rotary evaporator, or rotovap, is an instrument used to distill a solvent.(Everyone calls it a "rotovap" even though rotovap is a brand name). The purpose of distillation is to separate a given mixture into its components based on their respective volatilities, through the process of evaporation and condensation (liquid-gas-liquid).

Acetic Acid - Common Organic Chemistry

The common name for undiluted acetic acid is glacial acetic acid. With a melting/freezing point of around 16 C, acetic acid is not a suitable solvent for reactions that require cooling. In fact, when removing acetic acid by rotovap it tends to crystallize on the cold finger of the rotovap rather than dripping into the collection flask as a liquid.
