Investigation of Concentrated Ethanoic Acid Properties and Its Applications in Various Industries

The final step in the production of glacial acetic acid is the purification process. During purification, the acetic acid is distilled under reduced pressure to remove any water present in the solution. This distillation process results in the formation of glacial acetic acid, which is a highly concentrated form of acetic acid with a purity of at least 99.5%.

One of the most notable physical properties of glacial acetic acid is its melting point. It solidifies below 16.6 °C (62 °F), forming a crystalline solid that gives it the term “glacial.” In contrast, its boiling point is approximately 118.1 °C (244.6 °F). The relatively high boiling point demonstrates the strength of the hydrogen bonding between acetic acid molecules. These hydrogen bonds not only affect the melting and boiling points but also play a role in the acid's solubility characteristics and its behavior as a solvent in chemical reactions.

Однак, працюючи з гліцериновою оцтовою кислотою, потрібно дотримуватись обережності, оскільки це може бути корозійною речовиною. Захист очей, шкіри та органів дихання є важливими заходами безпеки під час роботи з цією речовиною. Вона може викликати подразнення шкіри та очей, тому завжди варто мати на руках відповідні засоби захисту.
