Dimethylformamide is a synthetic organic liquid used mainly as an industrial solvent in the manufacture of films, fibres, coatings and adhesives, in the purification of hydrocarbons in petroleum refining and in other chemical processes.

Acetic acid that contains a very low amount of water (less than 1%) is called anhydrous (water-free) acetic acid or glacial acetic acid. Its melting point is 16.6 °C. The reason it's called glacial is because it solidifies into solid acetic acid crystals just cooler than room temperature at 16.6 °C, which ice.
