What is glacial acetic acid?

Glacial acetic acid, usually refers to the higher purity of acetic acid, the chemical formula is CH-COOH. It is a colorless liquid with strong acidity and pungent odor, widely used in chemical, pharmaceutical, food and many other industries. The name of glacial acetic acid comes from its solid nature at low temperatures, because near 0 ℃, glacial acetic acid will solidify into white crystals, similar to ice and snow, hence the name "glacial acetic acid".

Physical properties and characteristics of glacial acetic acid

glacial acetic acid is a very important chemical raw material, which has a certain volatile and pungent odor. It is a colorless and transparent liquid at room temperature, its solubility is very strong, and it can be miscible with water, alcohols, ethers and other solvents. In a highly acidic environment, glacial acetic acid easily reacts with metals to produce hydrogen, so special care should be taken during storage and use.

What is the melting point of glacial acetic acid?

The melting point of glacial acetic acid is approximately 16.6°C. This melting point allows it to become solid at lower temperatures, hence the name "glacial acetic acid". When glacial acetic acid is at room temperature, it is usually a liquid, and only when the temperature is lower than its melting point, it will solidify into a solid. It should be noted that the melting point of glacial acetic acid is low, so when stored in a low temperature environment, it should be ensured that the temperature will not drop below 16.6°C to prevent it from curing and affecting the use.

Application of glacial acetic acid in industry

glacial acetic acid is one of the important chemical raw materials, which is widely used in many industrial fields. In the chemical industry, glacial acetic acid is commonly used to produce acetate esters, which are widely used in coatings, plastics, fibers and rubber. Glacial acetic acid can also be used as a solvent in a variety of chemical reactions, such as the production of vinyl acetate and other chemicals.

In the food industry, glacial acetic acid, as a raw material for edible vinegar, is widely used for seasoning and preservation. It is also used as an intermediate in chemical synthesis to produce important materials such as plastics and synthetic fibers.

Summary: Characteristics and application of glacial acetic acid

glacial acetic acid is an important chemical with a melting point of 16.6°C, high purity and strong acidity. As an important chemical raw material, glacial acetic acid plays an important role in many industries, not only for chemical synthesis, production of plastics and solvents, but also in food and pharmaceutical fields. Understanding the properties and melting point of glacial acetic acid is essential for its scientific use and storage.
