Overview

Acetic Acid Glacial (CAS 64-19-7) is a high-concentration acetic acid solution containing 99.5% or greater acetic acid content. This clear, colorless liquid with a characteristic pungent, vinegar-like odor serves as a critical raw material and intermediate in numerous industrial processes. The term "glacial" refers to its ability to crystallize at temperatures below 16.6°C, forming ice-like crystals. With the molecular formula C₂H₄O₂ and molecular weight of 60.05 g/mol, this versatile chemical compound offers excellent solubility properties and reactivity for diverse manufacturing applications.

Key Applications

  • Vinyl Acetate Monomer Production: Primary feedstock for manufacturing vinyl acetate, which is essential for producing polyvinyl acetate, polyvinyl alcohol, and various adhesives and coatings.
  • Chemical Synthesis & Solvents: Widely used as a polar protic solvent in organic synthesis reactions and as a precursor for manufacturing acetic anhydride, cellulose acetate, and various industrial esters.
  • Process Chemistry: Effective pH adjustment agent in industrial processes, analytical chemistry reagent, and etching agent for semiconductor and electronics manufacturing.
  • Specialty Manufacturing: Critical component in producing pharmaceuticals, food additives, textiles, and photographic chemicals where high purity and consistent quality are essential.

Safety & Handling

Acetic Acid Glacial has a flash point of 39°C and autoignition temperature of 485°C, requiring careful handling procedures. Always use appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and acid-resistant clothing. Ensure adequate ventilation in work areas as vapors can be irritating to respiratory systems. The chemical is highly corrosive and can cause severe burns to skin and eyes. Store away from incompatible materials such as strong bases, oxidizing agents, and metals. Emergency eyewash stations and safety showers should be readily accessible in work areas.

Storage & Shelf Life

Store Acetic Acid Glacial in tightly sealed, corrosion-resistant containers made from materials such as stainless steel, glass, or specialized plastics. Maintain storage temperatures between 15-25°C in a dry, well-ventilated area away from direct sunlight and heat sources. Avoid contact with metals, strong bases, alcohols, and oxidizing materials to prevent dangerous reactions. When properly stored in original containers, the product maintains stability and quality for extended periods. Always check container integrity regularly and follow proper inventory rotation procedures.

Frequently Asked Questions

What is acetic acid glacial (CAS 64-19-7) and what is it used for?
Glacial acetic acid (C2H4O2, CAS 64-19-7) is the nearly anhydrous form of acetic acid (typically ≥99.7% assay). It is used industrially and in laboratories as a solvent and reagent, and as a feedstock for producing acetate esters, acetic anhydride, vinyl acetate monomer, dyes, and other chemicals.
How should glacial acetic acid be stored and what is its typical shelf life?
Store tightly sealed in a cool, dry, well‑ventilated area away from oxidizers and bases, preferably below 25 °C and out of direct sunlight. Unopened drums or IBCs typically have a shelf life of 12–24 months depending on packaging and storage; consult the supplier certificate of analysis for exact dating.
What are the key safety and handling precautions for acetic acid glacial?
Glacial acetic acid is corrosive and can cause severe skin and eye burns and respiratory irritation; handle with chemical‑resistant gloves, splash goggles, face shield and acid-resistant clothing, and use local exhaust ventilation. Have eyewash and emergency showers available and follow the product SDS for first‑aid, spill control and neutralization procedures.
How do concentrations of acetic acid differ and why does concentration matter?
‘Glacial’ denotes near‑anhydrous acetic acid (≈99.7%); common aqueous grades include 80%, 50% and household vinegar (~4–8%). Higher concentrations increase chemical reactivity, corrosivity and fuming, so compatibility, PPE and shipping classifications change with concentration.
What documentation is available for glacial acetic acid?
Suppliers typically provide a Safety Data Sheet (SDS), Certificate of Analysis (COA), and Technical Data Sheet (TDS); additional documents such as transport paperwork, material declarations or regulatory compliance reports (e.g., REACH) can be supplied on request. Always review the SDS before use.
How is glacial acetic acid shipped and what packaging options are common?
Acetic acid is transported under UN2789 and may require corrosive and flammable placarding depending on concentration and local regulations; shipping requires appropriate hazardous‑goods documentation. Common packaging includes steel drums, HDPE drums, IBCs, ISO tanks for bulk, and glass or plastic bottles for laboratory quantities.
What materials is glacial acetic acid compatible or incompatible with?
Acetic acid is compatible with glass, PTFE, HDPE and some fluoropolymers; it attacks copper, brass, zinc and can corrode mild steel—stainless steel alloys (e.g., 316) may be acceptable at low concentrations and temperatures but should be validated. Always consult materials‑compatibility data for the specific concentration and operating conditions.
What are the typical technical specifications for glacial acetic acid?
Typical specifications for glacial acetic acid include assay ≥99.7%, water content ≤0.5%, density ~1.049 g·cm⁻3 at 20 °C, boiling point ~118 °C and melting point ~16.6 °C; exact limits vary by grade (technical, reagent, ACS). Consult the supplier COA or TDS for batch‑specific values.
Which industries and applications commonly use glacial acetic acid?
Common industries include chemical manufacturing, coatings and adhesives, specialty solvents, textiles, dyes and pigments, laboratory research and certain pharmaceutical syntheses (as a reagent or intermediate). It is used where a concentrated acetic medium or high‑purity reagent is required, not for direct food or medical use unless specifically certified.
How can I purchase glacial acetic acid and what is its availability?
Glacial acetic acid is widely available from chemical distributors in quantities from bottle‑scale to tanker loads; packaging options and lead times vary by region and supplier. For pricing, minimum order quantities, and regulatory requirements for large or cross‑border shipments, contact your supplier or sales representative with your required concentration and volume.
