Density is a crucial physical property that can influence the behavior of a substance during various processes, such as distillation, extraction, and crystallization. In the context of glacial acetic acid, its higher density compared to most organic solvents implies that it can be used efficiently as a reaction medium or to separate aqueous layers in multi-phase systems.

Le nom glaciaire vient effectivement du fait que l'acide acétique pur se fige à une température relativement élevée par rapport à d'autres substances chimiques. Il se solidifie à environ 16,6 °C, formant des cristaux transparents semblables à de la glace. Cette caractéristique visuelle est à l'origine du qualificatif de glaciaire, soulignant sa pureté ainsi que ses propriétés physiques distinctes. Dans cette condition, il se présente comme une substance visqueuse, dotée d'un caractère aigre prononcé et d'une odeur forte et piquante.

One of the most notable physical properties of glacial acetic acid is its boiling point, which is around 118.1 degrees Celsius (244.6 degrees Fahrenheit). This relatively high boiling point enables it to remain stable as a liquid under standard atmospheric conditions. Its melting point is approximately 16.6 degrees Celsius (61.8 degrees Fahrenheit), which means that at room temperature, it typically remains in a liquid state. However, when cooled to temperatures below its melting point, glacial acetic acid will solidify into a crystalline form, often referred to as glacial acetic acid. This characteristic allows for differentiation from diluted acetic acid solutions, which remain liquid at lower temperatures.
