Flammability Properties of Glacial Acetic Acid and Storage Precautions for Safety

Conclusion

L’acide acétique pur est communément appelé acide acétique glacial. Cette appellation peut prêter à confusion, mais elle fait référence à l’état physique de l’acide à température ambiante. À 16,6 °C, l’acide acétique pur se solidifie, devenant ainsi un liquide visqueux et clair qui ressemble à de la glace, d’où l’origine du terme « glacial ».

In the leather tanning industry, glacial acetic acid is used as a tanning agent. It can react with collagen fibers in hides and skins, converting them into more durable and water-resistant leather. Glacial acetic acid is also used in the removal of hair and flesh from hides, a process known as unhairing.

In addition to its chemical applications and hazards, the historical context of the term glacial acetic acid contributes to its importance. The term “glacier” is derived from the Latin word “glacies,” meaning ice. Early chemists noted the physical behavior of concentrated acetic acid, leading to the classification of its solid state as “glacial.” This use of the term has persisted, connecting contemporary chemical practice with the historical observations of scientists from previous centuries.
