Sodium Acetate, Anhydrous Cas No.127-09-3

Sodium acetate is anhydrous powder and granula. These two versions are chemically identical and differ only in physical form. The granula offers the properties of non-dustiness, improver wettability, higher bulk density and improver free-flowability.

COMMERCIAL INFORMATION

Grades

Sodium acetate anhydrous is available in USP E262 FCC or Technical grades.

Packing

Sodium acetate anhydrous is supplied in woven lined paper bags.

Storage and handling

The product should be stored and handled in its original packaging or in a suitable sealed container and kept in a clean and dry place. Storage conditions should preferably be a sheltered environment with limited temperature variations and low humidity levels. Direct contact of the package with water or any other liquid is likely to cause the product to cake. Pallets should not be stacked. Under normal conditions, the use of this product does not cause any undue health hazard. Precautions should be taken to prevent eye-and prolonged or repeated skin contact with the solid product or its solutions.

First aid

Eye contact: In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.

Skin contact: Wash with water. Remove contaminated clothing, which should be washed before re-use. Ingestion:

Wash out mouth with water. Obtain medical attention.

Fire hazard

Sodium acetate presents little fire hazard.

Application

Sodium acetate anhydrous is used in the pharmaceutical industry, as a buffer in the photographic industry and as a supplement for animal feeds to increase the milk fat production of dairy cattle(1).It is also used in the production of dye stuffs, as a polymerization catalyst, as a polymer stabilizer, as a flavouring agent, and in the manufacture of hydroxyl oximes, which are used as extractants in hydrometallurgy.
