Product Description
What Is Glacial Acetic Acid?
Glacial Acetic Acid represents the highly concentrated, nearly pure form of acetic acid (CH3COOH), typically consisting of 99-100% acetic acid. This colorless liquid has a pungent odor and solidifies into ice-like crystals when the temperature drops below 16.7°C.
Production Methods:
Methanol Carbonylation: In this process, methanol reacts with carbon monoxide under pressure, catalyzed by rhodium, to form glacial acetic acid.
Oxidation of Acetaldehyde: Acetaldehyde undergoes oxidation to form acetic acid when exposed to oxygen.
Glacial Acetic Acid is mainly utilized in chemical manufacturing, as a solvent, and as a reagent in numerous industrial applications.

User Asked Question:
Q: What distinguishes Glacial Acetic Acid from acetic acid in terms of concentration, purity, and common applications?
A: Glacial Acetic Acid is a highly concentrated, nearly pure form of acetic acid, typically containing 99%-100% acetic acid and is colorless with a pungent odor. In contrast, regular acetic acid, which is commonly found in vinegar, is a diluted solution containing around 4%-8% acetic acid by volume.
