Glacial Acetic Acid CAS 64-19-7 is a high-purity, anhydrous organic acid essential for industrial pH regulation and chemical synthesis. Chemically defined as ethanoic acid, this clear, colorless liquid serves as a critical acetylating agent in the production of vinyl acetate monomer (VAM), ester solvents, and terephthalic acid. In the textile industry, the material, commonly abbreviated as GAA, acts as a pivotal buffering agent and neutralizing component during dyeing and finishing processes. We provide competitive factory pricing and offer customized specifications for various purity grades and packaging solutions. Our bulk supply is fully supported by standard compliance documentation, including MSDS, TDS, COA, ensuring reliable integration into global supply chains.

Applications
Glacial Acetic Acid is a foundational chemical used across diverse industrial sectors:
Chemical Manufacturing (VAM & PTA)
- Vinyl Acetate Monomer (VAM): The primary precursor for paints, adhesives, and coatings (PVA).
- Purified Terephthalic Acid (PTA): Used as a solvent in the oxidation process to produce polyester fibers and PET plastics.
Textile & Dyeing
- Acidity Regulator: Acts as a pH regulator and dispersing agent in textile dyeing and printing to ensure color fastness and uniformity.
Food & Pharmaceutical
- Food Additive (E260): Used as an acidity regulator and preservative in vinegar production, sauces, and pickling (Food Grade only).
- Pharma Synthesis: Essential solvent and intermediate in the manufacturing of aspirin, paracetamol, and various antibiotics.
Quality Assurance (QA/QC)
- Purity Verification: Strict Gas Chromatography (GC) analysis is performed on every batch to ensure purity exceeds 99.8%.
- Impurity Control: Rigorous testing for reducing substances (like formic acid and aldehydes) to prevent side reactions in downstream applications.
- Certifications: Our supply chain is GMP compliant (for food/pharma grades) and operates under ISO 9001, ISO 14001, and ISO 45001 management systems.
Storage & Safety
Storage Conditions
- Temperature Control: Store above 17°C to prevent freezing (crystallization). If frozen, thaw gently using warm water or a heated room; do not apply direct flame.
- Ventilation: Keep in a cool, well-ventilated warehouse away from ignition sources.
- Material Compatibility: Store in high-density polyethylene (HDPE), stainless steel (316L), or aluminum containers. Avoid contact with carbon steel to prevent corrosion.
Safety Handling & PPE
Glacial Acetic Acid is classified as Corrosive (Class 8) and Flammable Liquid (Class 3).
- Respiratory Protection: Wear a full-face gas mask with organic vapor filters if vapor concentration is high.
- Skin & Eye Protection: Acid-resistant rubber gloves, chemical protective clothing, and splash-proof goggles are mandatory.
- First Aid: In case of skin contact, immediately remove contaminated clothing and rinse with plenty of water for at least 15 minutes.
FAQ - Technical & Supply Chain
-
Q:
Does this product meet the purity standards for "Glacial" grade?
A: Yes, Glacial Acetic Acid (CAS 64-19-7) refers specifically to the anhydrous grade with a purity typically exceeding 99.8%, distinguishable by its crystallization point near 16.6°C. -
Q:
Is this acid suitable for use as a pH regulator in textile dyeing?
A: This material is widely applied in textile wet processing as a buffering agent and pH adjuster to ensure uniform dye uptake and neutralization of alkaline residues on fabrics.
