Sodium Acetate,Anhydrous(White power)
SODIUM ACETATE,ANHYDROUS
CH3COONa
Sodium acetate anhydrous is a kind of white power or granule.These two versions are chemically identical and differ only in physical form. The granule is clean and offers the properties of non-dustiness, improved wettability, higher bulk density and improved free-flowability.
Grades
Sodium acetate anhydrous is available in USP / FCC / E262 grades.

Skin contact: Wash with water.Remove contaminated clothing, which should be washed before re-use.
Ingestion: Rinse the mouth with water. Obtain medical attention.
Fire hazard
Sodium acetate anhydrous 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. 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.
