What should be done if acetic acid leaks?
[Leakage Disposal]: Evacuate personnel in the contaminated area of glacial acetic acid leakage to a safe area, prohibit irrelevant personnel from entering the contaminated area, and cut off the source of fire. It is recommended that emergency handling personnel wear self-contained breathing appar...Read more -
What are the storage conditions for glacial acetic acid?
[Storage and Transportation Precautions]: Glacial acetic acid should be stored in a cool and well-ventilated warehouse. Keep it away from kindling and heat sources. The warehouse temperature should not exceed 30℃. In winter, anti-freezing measures should be taken to prevent freezing. Maintain the...Read more -
What kind of acid is glacial acetic acid?
Pure anhydrous acetic acid (glacial acetic acid) is a colorless, hygroscopic liquid with a freezing point of 16.6°C (62°F). Upon solidification, it forms colorless crystals. Although it is classified as a weak acid based on its dissociation ability in aqueous solutions, acetic acid is corrosive, ...Read more -
What changes occur when acetic acid is added to water?
When water is added to acetic acid, the total volume of the mixture decreases, and the density increases until the molecular ratio reaches 1:1, corresponding to the formation of orthoacetic acid (CH₃C(OH)₃), a monobasic acid. Further dilution does not result in additional volume changes. Molecul...Read more -
Why is it commonly referred to as glacial acetic acid?
Acetic acid is a colorless liquid with a strong, pungent odor. It has a melting point of 16.6°C, a boiling point of 117.9°C, and a relative density of 1.0492 (20/4°C), making it denser than water. Its refractive index is 1.3716. Pure acetic acid solidifies into an ice-like solid below 16.6°C, whi...Read more -
What are the main components of glacial acetic acid?
Acetic acid is a saturated carboxylic acid containing two carbon atoms and is an important oxygen-containing derivative of hydrocarbons. Its molecular formula is C₂H₄O₂, with the structural formula CH₃COOH, and its functional group is the carboxyl group. As the main component of vinegar, glacial ...Read more -
