Profile

Sodium Acetate, sodium salt of acetic acid, is a white or colourless crystalline compound, prepared by the reaction of acetic acid with sodium carbonate or with sodium hydroxide. There are commercially anhydrous salt or trihydrate form losing water at 58 C. Both are soluble in water and in ethoxyethane, and slightly soluble in ethanol.

Sodium acetate is used in the textile industry to neutralize sulfuric acid waste streams, and as a photoresist while using aniline dyes. It is also a pickling agent in chrome tanning, and it helps to retard vulcanization of chloroprene in synthetic rubber production.
