Name Sodium citrate dihydrate sodium citrate pentahydrate English name Trisodium citrate dihydratetrisodium citrate pentahydrate molecular weight 294.1357.1CAS No. 6132610461368586144612 density 1.79 g/cm1.62 g/ CM storage method Preservation at room temperature Closed storage at room temperature 02020202 Alias sodium citrate, is an organic compound with a white to colorless crystal in appearance. Odorless and has a cool, salty and spicy flavor. Stable at room temperature and air, slightly soluble in humid air, and weathering in hot air. Heating to 150℃ loses crystalline water. Soluble in water, soluble in glycerin, insoluble in alcohols and other organic solvents, decomposed by superheat, slightly deliquescent in humid environment, slight weathering in hot air, solution pH value of about 8.  02  0202 02 Sodium citrate is used as acidity regulator, flavoring agent, stabilizer in food and beverage industry; used as anticoagulant, expectorant and diuretic agent in industry; in detergent industry, it can replace sodium tripolyphosphate as an additive for non-toxic detergent; also used in brewing, injection, photography and plating, etc. 020202020202 020202Sodium citrate is used as a flavoring agent and stabilizer in the food and beverage industry; it is used as an anticoagulant, expectorant and diuretic in industry; in the detergent industry, it can replace sodium tripolyphosphate as a non-toxic detergent additive; chemically, it is an excellent chelating/complexing agent, and the industrial application of sodium citrate utilizes this characteristic. It is also used for brewing, injection, photography, and electroplating. 02 02 02 Sodium citrate is currently an important citrate salt. It is mainly produced by fermenting starchy substances to form citric acid and neutralizing it with alkalis. It has the following excellent properties: (1) Safe and non-toxic properties. Since the raw material for the preparation of sodium citrate is basically derived from food, * it is safe and reliable, and does not pose a risk to human health. The Food and Agriculture Organization of the United Nations and* WHO do not impose any restrictions on its daily intake and this product can be considered to be none. (2) It is biodegradable. Sodium citrate is diluted with a large amount of water in nature and partially becomes citric acid, and the two coexist in the same system. Citric acid is easily biodegradable through the effects of oxygen, heat, light, bacteria and microorganisms in water. Its decomposition pathway is generally converted to carbon dioxide and water through aconic acid, iconic acid, and citric anhydride. (3) It has the ability to complex metal ions. Sodium citrate has good complexing ability for Ca2+, Mg2+ and other metal ions, such as Fe2+, and other metal ions, such as Fe2+ plasma. (4) Excellent solubility performance, and the solubility increases with the increase of water temperature. (5) It has good pH adjustment and buffering performance. Sodium citrate is a weak acid and strong alkali salt. When combined with citric acid, it can form a strong pH buffer, so it is of great use in some situations where it is not suitable for a wide range of pH changes. In addition, sodium citrate also has excellent retarding and stabilizing properties. 020202
