Introduction	calcium acetate is an acetate of calcium with a special odor of white to brown or gray crystals. The common name for calcium acetate is calcium acetate. The moisture absorption of anhydrous calcium acetate is very good, so the common calcium acetate exists in the form of Ca(CH3COO)2.H2O. If an alcohol is added to a saturated calcium acetate solution, a semi-solid, flammable colloid is formed, much like can fuel products, such as Sterno. "California snow ball" is actually a mixture of calcium acetate and ethanol. The resulting colloidal color is white, stacked like a snow ball.
Chemical properties	calcium acetate decomposes above 160°C. Acetone Vapor and calcium carbonate are generated; It reacts sharply with strong acid to generate acetic acid smoke.
Application of	calcium acetate in kidney disease, blood phosphate concentration may be increased (hyperphosphatemia) and lead to some problems about the bone. Calcium acetate can be ingested in the daily diet to combine with excess phosphoric acid. The side effect of this method is abdominal pain. Calcium acetate is also a food additive and is mainly used in confectionery products.
Use	alkalinity agent; Nutritional supplement; Dough regulator; Curing agent; Yeast food; Anti-caking agent; Clotting agent; starter; Pectin adjuvant and improver; White pigment (food surface colorant). used in the production of acetone, acetic acid, Polyester Industry. used as food stabilizer, corrosion inhibitor, also used in the synthesis of acetate calcium acetate is acetate, a chemical reagent commonly used in many organic reactions. It is the main component of vinegar, contributing to its unique taste and smell. It is used in the synthesis of dye-sensitized solar cells. calcium acetate is a good dietary calcium fortifier with better absorption than inorganic calcium. Can be used for infant food, the use of 3.0~6.0g/kg (calcium, the same below); In cereals and their products for 1.6~3.2g/kg; it is 0.6-0.8g/kg in drinking and milk drinks. chelating agent; Antifungal agent; Stabilizer; Buffer; Flavoring agent; Preservative; Curing agent; Nutrition enhancer; PH regulator; Processing aid. used in analytical reagents, organic synthesis, printing and dyeing and pharmaceutical industry, or as a food stabilizer, chelating agent, antifungal agent, buffer, flavoring agent, corrosion inhibitor.

identification test	solubility soluble in water; Insoluble in ethanol. According to the OT-42 method. Identification of acetate the port of the hard glass test tube containing the sample was covered with a piece of filter paper slightly larger than the port of the test tube, which was wetted with a freshly prepared basic O-nitrobenzaldehyde test solution (TS-161). The test tube was suspended through a asbestos board and heated slowly with a gas flame. The filter shifted from blue to blue-green, indicating the presence of acetate. A 1:1 sulfuric acid was added to the sample and heated. The emission of acetic acid can be distinguished from the odor. Identify calcium plus ammonium oxalate test solution (TS-24) to the sample solution. A white precipitate is formed, which is soluble in hydrochloric acid but insoluble in acetic acid.
content analysis	determination of calcium content a sample of 2.5g (exactly 1 mg) is weighed accurately in a beaker, dissolve in 5ml of hot dilute hydrochloric acid solution (TS-117). After cooling, move to 250ml volumetric flask and mix with water. 50ml of this solution was transferred into a 400ml beaker, and TS-224 ml of water, 25ml of sodium hydroxide test solution (TS-154), 40mg of ammonium cyanurate indicator and 3ml of naphthol green test solution () were added. Titrated to dark blue with 0.05mol/L disodium EDTA. Each mL of 0.05mol/L EDTA disodium equivalent to calcium acetate (C4H6CaO4)7.909mg. Column (100 in diameter and 20cm in length) packed with strong acid type cation exchange resin (Amberlite IRl20, 1.5; Duolite c III;Dorvex 50; Lewis KS; Ion exchanger I Merck) for determination of acid content half of. Close the flow-out orifice of the column, add 0.1mol/L hydrochloric acid at the top until the resin is completely immersed, and place it for 1-2H. The acid was discharged, and the column was washed with about TS-167 ml of water until the 20ml of the eluate was added with 1 drop each of 0.02mol/L sodium hydroxide and the phenolphthalein test solution () and then turned red. 155g (accurate to 1mg) of a sample pre-dried to constant weight at 0.05 ° C. Was weighed, placed in a flask, dissolved with 15ml of water, and slowly injected into the column. The flask and column were washed with about 200ml of water, and the effluent was collected in an Erlenmeyer flask. Phenolphthalein test solution (TS-167) was added 2 drops and titrated with 0.1mol/L sodium hydroxide via a micro burette. Each mL of 0.1mol/L sodium hydroxide is equivalent to calcium acetate (C. H6CaO4)7.909mg.

exposure and health effects	route of exposure the substance can be absorbed into the body by inhalation and ingestion. Effects of short-term exposure the substance irritates the eyes, skin and respiratory tract. When the inhalation risk is diffused, the concentration of particulate pollution in the air is quickly reached.
production method	is obtained by reacting calcium carbonate with acetic acid. Method for preparing anhydrous calcium acetate: the refined powdered calcium carbonate is added to water, stirred into a suspension, and a small amount of glacial acetic acid is added in portions. After completion of the reaction, the filtrate was concentrated on a water bath, and a white solid, anhydrous calcium acetate, was precipitated from the viscous filtrate. after neutralized with pyrolignic acid (xyloacetic acid) and calcium hydroxide, the filtrate was evaporated to dryness and recrystallized. By acetic acid and calcium hydroxide or calcium carbonate reaction, filtered by concentrated, cooled to dihydrate salt (colorless crystals), heated to 84 ° C to a water salt (colorless crystals), anhydrous salt was obtained by heating to 100 °c. 900-1.3 mol/L milk of lime was prepared by washing, grinding and drying shells for 1H, roasting at 1.5-l000 ℃ for 2H, and adding water. It is then neutralized with acetic acid until it is clear, filtered, the filtrate is concentrated, and finally dried at 120-140 ° C. To give the final product with a yield of 91.28%. Add calcium carbonate powder in 20% acetic acid solution, until no longer escape CO2 gas, then add a small amount of calcium carbonate, heated to 80 ℃ reaction 2~3H filtrate with water bath heating concentration, at the same time, a small amount of 80% acetic acid was added, I .e., calcium acetate monohydrate was precipitated (dihydrate was precipitated after cooling the solution), and finally dried at 60-70 ° C. To obtain a finished product. 2CH3COOH+CaCO3→(CH3COO)2Ca+H2O+C02↑
