Glacial acetic acid (CH3COOH) is concentrated, essentially water-free acetic acid — a foundational industrial chemical used as a solvent, acidifier, and chemical intermediate. “Glacial” refers to the ice-like crystals it forms just below room temperature. This guide covers glacial acetic acid’s properties, grades, industrial uses, and safe handling, along with how to source it in bulk from RightPath Industries.
What Is Glacial Acetic Acid?
Glacial acetic acid is acetic acid at approximately 99.5% or higher concentration, as opposed to the dilute aqueous solutions found in products like vinegar. It is a clear, colorless liquid with a sharp, pungent odor, a boiling point near 118 °C, and a freezing point around 16.6 °C — meaning it can solidify in a cold warehouse. It is fully miscible with water and many organic solvents and is a moderately weak but corrosive acid.
Grades and Specifications
RightPath Industries supplies glacial acetic acid in production and high-purity grades. Typical specifications include assay of 99.5% or higher, low water content, and tight limits on heavy metals, chlorides, and other impurities for higher grades. ACS and reagent-type options are available where analytical purity is required, while production grade serves large-volume industrial processes. Specify your assay, packaging, and documentation needs (COA, SDS) when requesting a quote.
Industrial Uses
Glacial acetic acid is a versatile building block and processing chemical, used in applications such as:
- Chemical intermediate: feedstock for acetic anhydride, acetate esters, and vinyl acetate monomer.
- Solvent and acidifier: pH adjustment and reaction medium in chemical processing.
- Textiles and dyeing: used in dye baths and finishing processes.
- Cleaning and descaling: removes mineral scale and process residues.
- Laboratory and analytical work: reagent and titrant in a range of methods.
Safety and Handling
Glacial acetic acid is corrosive and combustible (flash point about 39 °C); it can cause severe skin and eye burns, and its vapors irritate the respiratory tract, so handle it with chemical-resistant gloves, goggles or a face shield, and adequate ventilation or local exhaust. Store in tightly closed, compatible containers in a cool, well-ventilated area away from strong bases, oxidizers, and heat; because it freezes near 16.6 °C, protect containers from low temperatures to avoid solidification and container stress. Keep water and spill-control materials available and review the current Safety Data Sheet before handling.
