Sodium acetate,anhydrous

Product Name Sodium acetate,anhydrous
CAS NO. 127-09-3
Molecular formula CH3COONa
Description Sodium acetate anhydrous is powder or 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.
Grades Sodium acetate anhydrous is available in USP / E262 / FCC / 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.
Application Sodium acetate Used in the field of medicine, photosensitive buffer photography industry, animal feed additive used to increase milk production rate, can also be used for dyeing and printing industry, polymerization catalysts, polymer stabilizers, flavors, is also used for oxime hydroxyl hydrometallurgical production. If necessary, provide detailed information on Application.
