Glacial acetic acid, also known as ethanoic acid, is a colorless liquid organic compound with a pungent odor. It is widely recognized for its distinctive sour taste and is a key component in many chemical processes. The term glacial refers to its ability to freeze at low temperatures, forming a solid that resembles ice. This property distinguishes it from diluted acetic acid solutions, commonly known as vinegar, which contain about 5% acetic acid.

Furthermore, the melting point of glacial acetic acid is an important parameter in the study of its phase diagram, which illustrates the equilibrium between different phases of a substance—solid, liquid, and gas—at various temperatures and pressures. This phase diagram is crucial for industrial applications where glacial acetic acid is involved in large-scale manufacturing processes, such as the production of synthetic fibers, plastics, and food additives. Maintaining the temperature of the system within specific limits ensures optimal performance and prevents unintended phase changes that could disrupt production.

In the laboratory, glacial acetic acid is employed as a solvent, particularly in the preparation of chemical reactions due to its high purity and ability to dissolve a wide range of organic compounds. However, its use requires careful handling due to its corrosive and volatile nature.
