What is Glacial Acetic Acid CAS 64-19-7?

Glacial acetic acid is essentially anhydrous acetic acid with a typical concentration of 99.5-99.8% or higher. It is a clear, colorless liquid with a sharp vinegar-like odor and is used as a chemical intermediate, solvent and acidifying agent.

Why is it called glacial?

The name refers to its ability to freeze into ice-like crystals at around 16.6 degrees Celsius. Because it is nearly water-free, it can solidify during cold-weather storage and transport, unlike diluted acetic acid.

What are the main applications?

It is used to produce vinyl acetate monomer, purified terephthalic acid, acetic anhydride, acetate esters and solvents. It also serves as an acidulant and process chemical in pharmaceuticals, textiles, rubber, coatings, food processing and water treatment.

Is this listing food grade?

The standard listing is industrial/glacial grade with a minimum concentration of 99.5-99.8%. Food grade is available on request, but concentrated acetic acid is corrosive and must be diluted and handled according to the intended food-use specification.

Which packaging is available?

It is supplied in 25 kg or 30 kg HDPE drums and 220 kg HDPE drums. Bulk loading and alternative packaging should be confirmed with the supplier before ordering.

What materials are suitable for storage and transfer?

Use compatible plastics such as HDPE or suitable stainless steel such as 316L. Carbon steel, aluminum and many other metals are not suitable for concentrated acetic-acid service, so piping, tanks and pumps must be selected for the actual concentration and temperature.

What specifications should be checked before ordering?

Confirm assay, water, formic acid, acetaldehyde, heavy metals, evaporation residue, color and permanganate time where relevant. Request the batch analysis, technical data and safety information before purchase.

How should glacial acetic acid be handled safely?

Use chemical-resistant gloves, eye and face protection, and adequate ventilation. Store away from strong oxidizers, bases, heat and ignition sources, and ensure spill containment. In cold conditions allow solidified material to thaw safely before transfer, and follow the safety information.

Product Description

Glacial Acetic Acid, CAS 64-19-7, also known as ethanoic acid or GAA, is essentially anhydrous acetic acid; the EC/EINECS number is 200-580-7.

Synonyms: glacial acetic acid; ethanoic acid; GAA; methane carboxylic acid; vinegar acid (concentrated).

CAS: 64-19-7.

Molecular formula: C₂H₄O₂.

Molecular weight: 60.05 g/mol.

EC number: 200-580-7.

It is a colorless, clear liquid with a strong pungent vinegar-like odor, corrosive and hygroscopic.

The assay (acetic acid) is 99.5–99.8% min (typically ≥99.8% for glacial grade); water content ≤0.20%.

Formic acid ≤0.05%; the freezing point is about 16.6 °C, giving ice-like crystals in cold conditions.

It is used to produce vinyl acetate monomer, purified terephthalic acid, acetic anhydride and acetate esters.

It is used as an acidulant and process chemical in pharmaceuticals, textiles, rubber, coatings, food processing and water treatment.

It is used as a chemical intermediate, solvent and acidifying agent.

Use compatible plastics such as HDPE or suitable stainless steel such as 316L for storage and transfer.

Confirm assay, water, formic acid, acetaldehyde, heavy metals, evaporation residue, color and permanganate time where relevant.

Store away from strong oxidizers, bases, heat and ignition sources; use chemical-resistant PPE, eye and face protection and spill containment.

Confirm packaging with the requested quantity and destination requirements.

Document requirements should be confirmed from the current specification, SDS, COA or other product-specific files.
