What Is the Boiling Point of Acetic Acid?
The Boiling Point of Acetic acid is 117.9 °C. At this temperature, liquid acetic acid will convert to a gaseous state under normal pressure.
Boiling point is very important in industrial processes such as chemical distillation, solvent recovery, purification, reaction temperature control, as well as storage and transportation planning. Glacial acetic acid has a relatively high boiling point compared with many other solvents, so it remains stable in most production environments.

What Is Acetic acid solvent Used For?
Industry and Manufacturing
The largest industrial use of acetic acid is in the production of vinyl acetate, a fundamental ingredient in paints, adhesives, and coatings. Acetic acid is also used to produce acetic anhydride, which is used in the production of synthetic fibers and film materials.
Pharmaceuticals and Medical
In the pharmaceutical field, high-purity acetic acid is used in the production of vitamins, antibiotics, and certain hormones. Diluted acetic acid solutions are used to treat ear infections.
Food Industry
As a food additive (labeled E260), acetic acid acts as a preservative and helps control acidity. It is found in pickles, condiments, and many processed foods.
Household Cleaning
White vinegar, a diluted solution of acetic acid, is a common household cleaner. It can remove mineral deposits, degrease, and disinfect a variety of surfaces.
Textiles and Leather
In fabric production, acetic acid helps regulate pH during the dyeing process, allowing color to penetrate the material more evenly.

Frequently Asked Questions (FAQ)
Q: Why is acetic acid's boiling point so high compared to other organic solvents?
A: Acetic acid forms stable dimers through hydrogen bonding between two molecules. This dimerization effectively doubles the molecular weight in the liquid phase, requiring significantly higher temperatures to achieve vaporization. The boiling point of 117.9°C is much higher than ethanol (78.4°C) or acetone (56°C) with similar molecular weights.
Q: How does glacial acetic acid (GAA) differ from regular acetic acid?
A: "Glacial" refers to 99.5%+ pure anhydrous acetic acid. It gets its name because it solidifies into ice-like crystals at 16.6°C (61.9°F), just below room temperature. Technical-grade acetic acid typically ranges from 80-99% purity, while vinegar contains only 4-8% acetic acid in water.
Q: What is the density of 99% glacial acetic acid CAS 64-19-7?
A: 99% glacial acetic acid has a density of approximately 1.050 g/cm³ at 20°C. The difference between 99% and 100% purity is minimal (less than 0.1%) because water and acetic acid have very similar densities at this concentration range.
Q: Is acetic acid chemical heavier than water?
A: Yes, pure acetic acid (1.049 g/cm³) is approximately 5% denser than water (1.000 g/cm³ at 4°C). However, when mixed with water, the density first increases to a maximum at ~79% concentration before decreasing as dilution continues.
