Sodium diacetate Chemical Properties,Usage,Production

Chemical Properties

Sodium diacetate has the odor of acetic acid. It is a molecular compound of sodium acetate and acetic acid. The pH of a 1 in 10 solution is between 4.5 and 5.0.

Chemical Properties

White crystals; acetic acid odor. Decom- poses above 150C. Soluble in water; slightly soluble in alcohol; insoluble in ether. Combustible.

Occurrence

Acetic acid or acetates are present in most plant and animal tissues in small, but detectable amounts.

Uses

Sodium acetate buffer solution has been used for the precipitation of DNA. It has also been used as a component of supporting electrolyte for electrochemical sensor.

Uses

Acetic acid in solid form; sequestrant; food preservative to inhibit molds and rope-forming bacteria in bread: Glabe, Food Ind. 14, no. 2, 46 (1942).

Uses

Sodium Diacetate is a preservative, sequestrant, acidulant, and fla- voring agent that is a molecular compound of sodium acetate and acetic acid which yields acetic acid. it is a white crystalline powder which is hygroscopic. it functions against mold and bacteria and is used in bread. it is also termed sodium hydrogen diacetate.

General Description

Sigma′s Sodium Acetate Buffer is a 3M solution prepared with 18 megaohm water and filter-sterilized.

Flammability and Explosibility

Non flammable

Agricultural Uses

Fungicide, Bactericide: Sodium diacetate is a fungicide and bactericide registered to control molds and bacteria, thereby preventing spoilage in stored grains. The pesticide is applied to hay as a dust or soluble concentrate (liquid spray) during the baling process. It is applied to silage as a fermentation "aid" to preserve the quality of field corn, alfalfa, sorghum, oats and grasses, stored in silos. Sodium diacetate is composed of acetic acid and sodium acetate. It dissociates to acetate, sodium and hydrogen ions, normal components of plants and animals, and of human foods. Acetates are formed in living organisms during the metabolism of food. Acetates and acetic acid have long been used in both human and animal foods, without significant adverse effects. Sodium diacetate is also used as an antimicrobial agent in baked goods and other foods, and in medicine and cosmetics manufacturing as a freshener, flavoring and pH regulator. Not listed for use in EU countries. 126-96-5. Registered for use in the U.S.
