Product Description


Sodium Acetate is manufactured by the reaction of Soda Ash (or caustic soda) with Acetic Acid. The reaction is exothermic. To control heat the reaction is done in a very large volume of liquor.

Na2CO3 + 2CH3COOH → 2CH3COONa + H2O +CO2 and Heat.

NaOH + CH3COOH → CH3COONa + H2O and Heat.

Crystals are formed after evaporation of the reacted liquor and the material is centrifuged and dried. Now KOLOD has become one of the most competitive and major manufacturer of Sodium acetate in both technical grade, food grade and pharma grade Sodium acetate, both anhydrous (CH3COONa) and trihydrate (CH3COONa.3H2O).

Here are the standards of various grades of Sodium acetate produced by Jiangsu Kolod Food Ingredients Co., Ltd..

Sodium Acetate USP Specifications

Sodium Acetate USP
C2H3NaO2-3H2O 136.08

Assay- Sodium Acetate contains three molecules of water of hydration, or is anhydrous. It contains not less than 99.0 percent and not more than 101.0 percent of C2H3NaO2, calculated on the dried basis.
Packaging and storage- Preserve in tight containers.
Labeling- Label it to indicate whether it is the trihydrate or is anhydrous. Where Sodium Acetate is intended for use in hem dialysis, it is so labeled.
Identification- A solution responds to the test for Sodium and for Acetate.
pH: between 7.5 and 9.2, in a solution in carbon dioxide-free water containing the equivalent of 30 mg of anhydrous sodium acetate per mL.
Loss on drying- Dry at 120 to constant weight: the hydrous form loses between 38.0% and 41.0% of its weight, and the anhydrous form loses not more than 1.0% of its weight.
Insoluble matter- Dissolve the equivalent of 20 g of anhydrous sodium acetate in 150 mL of water, heat to boiling, and digest in a covered beaker on a steam bath for 1 hour. Filter through a tarred filtering crucible, wash thoroughly, and dry at 105 : the weight of the residue does not exceed 10 mg (0.05%).
Chloride- A portion equivalent to 1.0 g of anhydrous sodium acetate shows no more chloride than corresponds to 0.50 mL of 0.020 N hydrochloric acid (0.035%).
Sulfate- A portion equivalent to 10 g of anhydrous sodium acetate shows no more sulfate than corresponds to 0.50 mL of 0.020 N sulfuric acid (0.005%).
Calcium and magnesium- To 20 mL of a solution containing the equivalent of 10 mg of anhydrous sodium acetate per mL add 2 mL each of 6 N ammonium hydroxide, ammonium oxalate TS, and dibasic sodium phosphate TS: no turbidity is produced within 5 minutes.
Potassium- Dissolve the equivalent of 3 g of anhydrous sodium acetate in 5 mL of water, add 1N acetic acid drop wise until the solution is slightly acidic, and then add 5 drops of sodium cobalt nitrite TS: no precipitate is formed.
Aluminum: (where it is labeled as intended for use in hem dialysis)- the limit is 0.2µ =g per g.
Heavy metals-the limit is 0.001%.
Organic volatile impurities: meets the requirements.
