glacial acetic acid (CAS 64-19-7) Specification

uses of glacial acetic acid (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.

How do you store glacial acetic acid (CAS 64-19-7)?

Indoor storage
Glacial acetic acid (CAS 64-19-7) should be stored in a dry, well-ventilated indoor environment, avoiding direct sunlight, the temperature should not be higher than 30 degrees Celsius, and the relative humidity should be kept at 50%~60%. If the ambient humidity is too high, glacial acetic acid may absorb the moisture in the air, thus affecting its quality and using effect.

Sealed storage
During storage, sealed containers should be used to store glacial acetic acid (CAS 64-19-7) to avoid substances such as moisture, oxygen and impurities in the air entering into the containers and affecting its quality and stability. Sealed containers such as glass bottles or polyethylene containers are usually recommended for the storage of glacial acetic acid.

Storage away from light
glacial acetic acid (GAA) should be stored in an environment protected from light, i.e., it should not be directly exposed to sunlight or strong light to avoid problems such as oxidation, degradation or color change.

Keep away from flammable substances
Because glacial acetic acid (GAA) has flammable and explosive properties, contact with flammable substances should be avoided during storage, and care should be taken to keep the containers tightly sealed in order to avoid any danger.

In conclusion, the correct storage conditions can ensure the quality and stability of glacial acetic acid (GAA), so as to better play its role. In the process of use, it is also necessary to strictly follow the requirements on the product instructions and labeling to avoid accidents.
