Acetic Acid Glacial - Food Grade

Product Overview

Glacial acetic acid (CAS 64-19-7) is a highly concentrated, anhydrous form of ethanoic acid with the chemical formula C2H4O2 and a molecular weight of 60.05. Known for its characteristic pungent odor and clear, colorless appearance, this organic compound is a vital component across numerous manufacturing sectors. Alliance Chemical supplies this chemical to meet the rigorous demands of industrial processing, ensuring consistency, reliability, and high purity in every batch. As an essential chemical intermediate, it serves as a cornerstone reagent in the synthesis of vinyl acetate monomer, acetic anhydride, and various acetate esters that drive modern manufacturing.

Our supply of this product is meticulously managed to maintain its anhydrous state. Since glacial acetic acid crystallizes at temperatures below 61.9 °F, handling and logistics require precise temperature controls, a factor that Alliance Chemical manages with professional expertise. Whether utilized as a solvent, a pH adjuster, or a precursor in chemical synthesis, our glacial acetic acid provides the exact specification profile necessary to protect your process integrity. We provide a Certificate of Analysis (COA) available upon request and a Safety Data Sheet (SDS) with every order to ensure total compliance and peace of mind.

Why This Grade

Selecting the correct purity grade of glacial acetic acid is critical to preventing process deviations and ensuring the high quality of your finished products. This specific high-purity FCC and manufacturing-compliant grade is engineered with stringent limits on heavy metals, chlorides, and sulfate impurities, which are common points of failure in lesser technical grades. In complex industrial processes, even trace amounts of metallic contaminants can act as unwanted catalysts, poisoning expensive process catalysts or initiating runaway side reactions. By utilizing our high-specification product, process engineers can eliminate variability and maintain strict control over reaction kinetics, ensuring reproducible yields shift after shift.

Furthermore, the moisture content of glacial acetic acid must be kept exceptionally low. In applications such as specialized solvent formulations or polyester polymer synthesis, the presence of excess water can severely impede chemical reactions, shift equilibria unfavorably, or cause hydrolytic degradation of polymer chains. Utilizing a generic or lower-grade alternative often results in premature equipment corrosion, product discoloration, and final outputs that fail quality control standards. This high-purity grade ensures that your chemical systems operate at peak efficiency without the risk of moisture-induced side reactions or contamination-driven product failures, safeguarding your operational output.

Industrial Applications

• Chemical Synthesis Feedstock: Used as a critical precursor in the synthesis of vinyl acetate monomer (VAM), which is the primary building block for adhesives, paints, and paper coatings.
• Textile Wet Processing: Serves as a reliable neutralizing agent and pH regulator in textile dyeing and finishing processes, ensuring optimal dye exhaustion and color fastness.
• Industrial Descaling and Cleaning: Utilized in industrial-strength cleaning formulations to dissolve carbonate scale and clean metal surfaces without causing excessive pitting or structural degradation.
• Agricultural Formulation Adjuvant: Employed in the manufacture of agricultural chemicals and adjuvants, where precise pH control and formulation stability are vital for field efficacy.
• Polyester Intermediate Manufacturing: Acts as a solvent and reactant in the production of purified terephthalic acid (PTA), a key raw material for polyethylene terephthalate (PET) plastics.

Hazmat & Shipping

Glacial acetic acid is a regulated hazardous material due to its corrosive and flammable properties. Under DOT regulations, it is classified as UN2789, Hazard Class 8, and is assigned to Packing Group II. The official proper shipping name is Acetic acid, glacial. It is designated with the signal word Danger and is associated with hazard statements H226 (Flammable liquid and vapor) and H314 (Causes severe skin burns and eye damage). Alliance Chemical maintains full compliance with all hazmat shipping standards, utilizing certified packaging and reliable carriers to deliver your product safely and securely.

Handling this compound requires strict adherence to safety protocols and the use of appropriate Personal Protective Equipment (PPE) to mitigate risks. Personnel must wear chemical-resistant gloves (such as butyl rubber or neoprene), splash-resistant safety goggles, a full face shield, and protective clothing to guard against dermal and ocular contact. In areas where vapor concentrations may exceed permissible exposure limits, a NIOSH-approved respirator equipped with organic vapor cartridges must be utilized. Ensure proper ventilation is maintained in all work areas, and keep emergency eyewash stations and safety showers readily accessible in the immediate vicinity of handling operations.

Handling & Storage

Storage of glacial acetic acid requires careful consideration of its physical properties, particularly its melting point of 61.9 °F. To prevent crystallization, the product should be stored in a temperature-controlled environment maintained between 65 °F and 90 °F; if freezing occurs, gentle warming is required to liquify the material without applying direct heat. The chemical is highly corrosive to many metals, including mild steel, copper, and brass; therefore, it must be stored in compatible containers constructed from high-density polyethylene (HDPE), glass, or specific grades of stainless steel. Keep containers tightly closed and isolated from strong oxidizing agents, strong bases, and active metals to avoid hazardous chemical reactions.
