62-54-4 Usage

Production method

It is obtained by the reaction between calcium carbonate and acetic acid. Preparation method of anhydrous calcium acetate: the refined powder of calcium carbonate is added to the water, stirred into a suspension; added separately of a small amount of glacial acetic acid. After completion of the reaction, the filtrate was concentrated in a water bath and a white solid, anhydrous calcium acetate, was precipitated from the viscous filtrate.
It is obtained by the neutralization between coke acid (wood acetic acid) and calcium hydroxide, followed by the evaporation of the filtrate and recrystallization.
It is obtained by the reaction between the reaction between acetic acid and calcium hydroxide or calcium carbonate. Filter, concentrate and cool to obtain the dihydrate (colorless crystal), heated to 84 °C in a water salt (colorless crystal), heated to 100 °C to obtain the anhydrous salt.
Shellfish can be taken as raw materials, washed, crushed and dried for 1 h, subjecting to barbecue for 2 hour at 900~l000 ℃, then being added water to make a 1.3~1.5mol/L lime milk. And then neutralized with acetic acid to clarify, filter with the filtrate concentrated, and finally dried at 120~140 °C to get the final product with a yield of 91.28%.
To a 20% acetic acid solution, add calcium carbonate powder to until there is no longer any CO2 gas escaping, then add a small amount of calcium carbonate, heated  80 ° C for reaction of 2-3h. The filtrate was heated and concentrated with water bath while adding a small amount of 80% acetic acid at the same time to precipitate the calcium acetate monohydrate (what precipitated after the cooling of the solution is dihydrate), and finally dried at 60~70 ℃to derive the products.

Uses

1.  Calcium acetate is used in the industry for the manufacturing of acetone, acetic acid and polyester.
2.  It can be used as food stabilizers, corrosion inhibitors as well as for the synthesis of acetate
3.  It is used as analysis reagents as well as the synthesis of acetate.
4.  Calcium acetate is a excellent food calcium fortifier with better absorption effect than inorganic calcium. It can be used for infant food with the usage amount of 3.0~6.0g/kg (in terms of elemental calcium, the same as below); in cereals and their products, the usage amount is 1.6~3.2g/kg; in drinks and milk drinks, it is 0.6~0.8 G/kg.

Toxicity

ADI is not subject to restrictive regulations (FAO/WHO, 2001).
GRAS (FDA, §181.29, §182.6197, § 184.1185, 2000).
LD50: 52 mg/kg (mouse, subcutaneous).

Identification test

Solubility: easily soluble in water; insoluble in ethanol. Determine it according to OT-42 method.
Identification of acetate salt
Use a piece of filter paper (slightly large than the mouth of the test tube) to cover the mouth of the hard glass test tube containing the sample. The filter paper was wetted with a freshly prepared basic o-nitrobenzaldehyde test solution (TS-161). The test tube is hung up through the asbestos board, further subjecting to slow heating with a gas flame. Filter paper will turn from blue to blue-green, indicating the presence of acetate.
Supply 1: 1 sulfuric acid to the sample after heating. Acetic acid can be discerned by odor.
Identification of calcium: add ammonium oxalate solution (TS-24) to the sample solution for forming white precipitate, soluble in hydrochloric acid, but insoluble in acetic acid.

Content analysis

Determination of calcium: accurately weigh 2.5 g in the beaker (accurate to l mg), dissolve in 5 ml of hot dilute hydrochloric acid test solution (TS-117). After cooling, transfer it to a 250ml volumetric flask and mix with water. 50 ml of this solution was transferred to a 400 ml beaker; successively add 100 ml water, 25 ml sodium hydroxide solution (TS-224), 40 mg ammonium purpurinate indicator and 3 ml naphthol green test solution (TS-154). Apply 0.05mol/L EDTA disodium for titration to dark blue color. Each mL of 0.05mol/L EDTA disodium is equivalent to 7.909 mg of calcium acetate (C4H6CaO4).
Method for determination of acid content; apply strong acid type cation exchange resin (Amberlite IRl20, 100; Duolit c III; Dorvex 50; Lewatit KS; Ion Exchanger I Merck) to fill with half of a column (1.5 cm in diameter, 20 cm in length). Close the discharge orifice of the column. Add 0.1mol/L hydrochloric acid from the top to until the resin was completely submerged, placed for 1~2h. The acid was drained, and the column was rinsed with water (about 1000 ml) until when 20 ml elute exhibits red color after being added of one drop of 0.02 mol/L sodium hydroxide and phenolphthalein test solution (TS-167). Weigh 0.05 g sample pre-dried at 155 ℃to constant weight (accurate to 1mg), place in the flask, add 15 ml water for dissolving and slowly add into the column. The flask and column were washed with about 200 ml of water, and the effluent was collected in an Erlenmeyer flask. Add 2 drops of phenolphthalein test solution (TS-167). Apply 0.1mol/L sodium hydroxide through the micro-titration for titration. Each mL of 0.1 mol/L sodium hydroxide corresponds to 7.909 mg of calcium acetate (C.H6CaO4).

Solubility in water (g / 100ml)

Dissolved grams per 100 ml of water at different temperatures (° C):
37.4 g/0 ° C; 36 g/10 ° C; 34.7 g/20 ° C; 33.8 g/30 ° C; 33.2 g /
32.7 g/60 ° C; 33.5 g/80 ° C; 31.1 g/90 ° C; 29.7 g/100 ° C

Definition

ChEBI: The calcium salt of acetic acid. It is used, commonly as a hydrate, to treat hyperphosphataemia (excess phosphate in the blood) in patients with kidney disease: the calcium ion combines with dietary phosphate to form (insoluble) calcium phosphate, which is excreted in the faeces.

Uses

Pharmaceutic aid (buffering agent).

Purification Methods

Recrystallise it from water (3mL/g) by partial evaporation in a desiccator. [Beilstein 2 IV 113.]
