What is Sodium acetate?

The basic characters of sodium acetate

Sodium acetate molecular formula: C2H3NaO2

Molecular weight: 82.03 sodium acetate

Sodium acetate point: 324 ℃

CAS NO: 127-09-3

Sodium acetate is a kind of colorless and tasteless Crystallization, it can be weathered in the air, and it is flammable. Sodium acetate is soluble in water, ether and ethanol. Sodium acetate trihydrate melting point is 58 ℃, relative density is 1.45, autoignition temperature is 607.2 ℃. In 123 ℃ to 3 molecules of water to obtain anhydrous sodium acetate. Sodium acetate anhydrous melting point is 324 ℃, relative density is 1.528.

Production method of sodium acetate

Calcium acetate and Soda by the metathesis reaction, into sodium acetate, the reaction solution was concentrated to 26 ° Be, plus active carbon and then cooling and crystallization, centrifugal separation derived products. When the time required to obtain anhydrous sodium acetate, sodium acetate will re-melt crystallization, vacuum filter, crystal liquor on the stainless steel tank and cooled and then centrifuged; suction filtration; drying, heating electricity so crystal dehydration, drying, dry goods. Acetic acid and caustic soda can also be used directly by the reaction of sodium acetate.

Sodium acetate purposes

Esterification agent for organic synthesis and photography medicines, pharmaceutical, printing and dyeing mordant, buffer, chemical reagent, meat preservation, pigments, leather tanning and many other aspects. It can be also used to produce a variety of chemical products, such as furan acrylic acid, acetic acid esters and the like. The product as seasonings buffer, ease the bad odor and prevent discoloration, a certain antifungal effect. Sodium acetate is also used for sauces, pickles, mayonnaise, fish cake, sausage, bread, sticky cakes and other sour agent. Sodium acetate mixed with methyl cellulose, phosphate for improving sausage, bread, such as the preservation of sticky cake.

Finally, what I want to minder you is that there are three levels of anhydrous sodium acetate, Pharmaceutical grade, food grade, industrial grade. Food should be used for food-grade.
