Acetic acid (GAA) is a versatile organic compound and one of the most important organic chemicals in modern industry. It is renowned for its distinctive vinegar-like odor and excellent chemical properties, playing a crucial role in chemical manufacturing, food processing, pharmaceuticals, textiles, coatings, and agriculture. This article will introduce the properties and uses of acetic acid (Glacial) CAS 64-19-7.
What Is Acetic acid CAS 64-19-7?
Acetic acid is also known as ethanoic acid, ethylic acid, vinegar acid, and glacial acetic acid (GAA). Acetic acid is a byproduct of fermentation, and gives vinegar its characteristic odor. It is a colourless liquid with distinct sour taste and pungent odour. It is a simple carboxylic acid (an organic compound that has a carboxyl group (-COOH) characterised by its acidity, polarity, and high boiling point). It is an organic carboxylic acid with the chemical formula: ch3cooh.
Synonyms:
- Glacial acetic acid
- Ethanoic acid
- Methanecarboxylic acid
- Vinegar acid
- AcOH
- AA/GAA

Chemical Properties:
- Acidity:
Acetic acid (CAS 64-19-7) ionizes in water, producing hydrogen ions (H⁺). It turns blue litmus paper red, indicating its acidity. However, because ethanoic acid does not completely ionize in aqueous solution, it is a weak acid.
- Reaction with Sodium Bicarbonate:
It reacts with sodium bicarbonate to produce carbon dioxide.
What Is Acetic acid solvent Used For?
1. Production of Vinyl Acetate Monomer (VAM)
The production of vinyl acetate monomer (VAM) is one of the most important applications of acetic acid solvent. VAM is a fundamental raw material for manufacturing various downstream products, including adhesives, paints, coatings, packaging materials, textile adhesives, and emulsion resins. The booming global construction and packaging industries continue to drive up the demand for VAM, thereby driving the continuous growth of the acetic acid market.
2. Production of Acetic Anhydride
Acetic anhydride is an important chemical derivative synthesized from glacial acetic acid. It is widely used in many industrial sectors, primarily including pharmaceuticals, aspirin processing, cellulose acetate manufacturing, and the synthesis of dyes, fragrances, and other compounds. Such a wide range of applications makes acetic acid an indispensable raw material for the pharmaceutical industry and the manufacture of specialty chemicals.
3. Solvent Applications
Due to its strong dissolving power, acetic acid (CAS 64-19-7) is a high-performance industrial solvent. Glacial acetic acid is widely used in ink production, paint and coating manufacturing, textile dyeing, rubber processing, resin synthesis, and industrial cleaning formulations. Notably, glacial acetic acid is particularly suitable for industrial applications requiring high-purity solvents.
4. Food Industry Applications
Food-grade acetic acid liquid is a common food additive with multiple functions, serving as an acidity regulator, preservative, flavor enhancer, and pickling agent. Diluted acetic acid is the main component of vinegar and is widely used in sauces, pickled vegetables, various condiments, and general food preservation. Due to its inherent antibacterial properties, acetic acid can effectively extend the shelf life of many foods.
5. Pharmaceutical Industry
It is widely used in pharmaceutical production processes. Its main applications include the production of pharmaceutical intermediates, buffer solutions, and antibiotics, as well as vitamin synthesis and the preparation of chemical reagents. Its stable chemical properties allow for reliable and controlled chemical synthesis in laboratory research and large-scale industrial pharmaceutical production.
6. Textile Printing and Dyeing Industry
In the textile printing and dyeing industry,glacial acetic acid (GAA) is mainly used for pH adjustment, color fixing, fabric finishing, textile printing, and synthetic fiber processing. It optimizes the uniformity of dye adsorption and improves the overall quality of finished textiles throughout the production process.
7. Agriculture and Animal Feed Industry
Acetic acid also has practical applications in agriculture and animal husbandry. Its main applications include silage preservation, feed acidification, industrial cleaning and disinfection, and the production of agrochemicals.
