10l rotovap acetic acid

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.
