What is acetic acid 64 19 7?
Glacial acetic acid, also known as anhydrous acetic acid, is a carboxylic acid classified as a weak acid. It consists of a hydrocarbon chain linked to a carboxyl group, with the molecular formula C₂H₄O₂. Acetic acid (GAA CAS 64-19-7) solution is a vital chemical raw material widely used in pharmaceuticals, organic chemistry, organic synthesis, synthetic fibers, polymer chemistry, pesticides, leather processing, rubber, and other industries.

Acetic Acid (GAA) Properties
Physical Properties of Acetic Acid (GAA)
- State and Appearance: Acetic Acid (GAA) is a colorless, transparent liquid at standard temperature and pressure, possessing a strong pungent odor (i.e., vinegar smell) and high volatility.
- Solubility: Infinitely miscible with polar solvents such as water, ethanol, and diethyl ether. This property enables its widespread use in solution-based applications.
- Boiling Point and Melting Point: Boiling point approximately 117.9°C (247.8°F), melting point approximately 16.6°C (32.3°F). At low winter temperatures, pure acetic acid crystallizes into an ice-like solid, hence its alternative name "glacial acetic acid."
- Corrosivity: Possesses weak acidity. At higher concentrations (e.g., glacial acetic acid), it exhibits corrosive effects on skin, eyes, and mucous membranes. Prompt rinsing with water is required upon contact.
Acetic Acid (GAA) Chemical Properties
- Acidity: GAA is a weak acid that partially ionizes in water to release H⁺ (ionization equation: CH₃COOH ⇌ CH₃COO⁻ + H⁺). It reacts with bases (e.g., NaOH) and carbonates (e.g., Na₂CO₃) to form salts and water. For instance, reacting with baking soda produces carbon dioxide gas (commonly used for descaling).
- Esterification Reaction: Under conditions of heating and catalysis by concentrated sulfuric acid, it reacts with alcohols (e.g., ethanol) to form esters (e.g., ethyl acetate) and water. This reaction is a fundamental principle in the preparation of fragrances and solvents.
- Stability: Stable at room temperature and resistant to decomposition; however, under high temperatures or in the presence of strong oxidizing agents, it can be oxidized to carbon dioxide and water.
Main uses of acetic acid (GAA CAS 64-19-7)
Glacial Acetic Acid (GAA) is acetic acid with a concentration ≥99%, named for its low-temperature solidification into ice-like crystals. Its applications fall into four major categories:
Industrial Applications
- Synthesis of vinyl acetate (used in paint and adhesive manufacturing), terephthalic acid (raw material for PET plastics), etc. Approximately 60% of global glacial acetic acid is consumed in chemical production.
- As a pH adjuster in textile dyeing to ensure uniform dye adsorption.
Laboratory Settings
- Acetic Acid (GAA CAS 64-19-7) solution is used to prepare buffers (e.g., acetic acid-sodium acetate buffer, pH 4.0-5.5) for biochemical experiments.
- A 3%-5% dilution is typically employed for protein precipitation.
Medical Applications
- Treating plantar warts: Apply 80%+ concentration directly to the wart for cauterization. Professional administration is required to prevent skin burns.
- Disinfecting otitis externa: Dilute to 2%-3% for use in inhibiting fungi and bacteria.
Food Additives
Food-grade acetic acid (GAA CAS 64-19-7) solution (E260) is used in pickling and seasonings, with a safe limit of 10g/kg.
