Category : Other Chemicals/Others
CAS NO : 6132-4-3 EC NO : MF : MW : Specification : White Powder Packing : 500g/bottle Product description : The advantages of the properties and uses of sodium citrate Sodium citrate, white crystalline or granular powder. Odorless, with a cool, salty and spicy taste. At room temperature and in humid air, there is slight solubility, and weathering occurs in hot air. Soluble in water, insoluble in ethanol. The aqueous solution is weakly alkaline. Sodium citrate is currently the most important citrate salt in industry, with extremely wide applications, and can be used in industries such as food, medicine, environmental protection, electroplating, and brewing. The properties and uses of sodium citrate 1. The performance of sodium citrate Sodium citrate is currently the most important citrate salt, mainly produced by fermentation of starch substances to produce citric acid, which is then neutralized with alkaline substances, and has various unique and excellent properties. (1) Safe and non-toxic performance. (2) Has good pH regulation and buffering performance. (3) Excellent solubility, and solubility increases with increasing water temperature; (4) Sodium citrate has biodegradability. After being diluted with a large amount of water in nature, some of it becomes citric acid, and the two coexist in the same system. Citric acid is easily biodegradable in water through the action of oxygen, heat, light, bacteria, and microorganisms. 2. The use of sodium citrate Sodium citrate has various excellent properties mentioned above, making it widely used. Currently, citric acid and its sodium citrate are widely used in the food industry, pharmaceutical industry, chemical industry, and other fields 2.1 In terms of food, sodium citrate is used as a food additive with the highest demand, mainly as a seasoning agent, buffer, emulsifier, expanding agent, stabilizer, and preservative; In addition, sodium citrate is used in combination with citric acid as a gelling agent, nutritional supplement, and flavoring agent for various jams, jellies, juices, beverages, cold drinks, dairy products, and pastries. 2.2 In the field of medicine, sodium citrate has a wide range of uses. By utilizing the characteristic of forming soluble complexes between citrate ions and calcium ions, it can be used as an anticoagulant and transfusion agent for the preservation and processing of blood products. Sodium citrate is used as a preservative to preserve drugs such as syrup. Sodium citrate injection, like methylate, is used to correct the acidity of blood, body fluids, and urine, as a expectorant, diuretic, and expectorant. Adding a certain amount of sodium citrate to detergent can significantly increase its cleaning ability. Liquid detergents containing sodium citrate have excellent washing performance. Some specialized cleaning agents containing sodium citrate are non corrosive to certain metal utensils; Some specialized detergents containing sodium citrate can produce a shiny new metal surface after cleaning, and the waste liquid after cleaning can be recycled and reused after treatment, reducing washing costs. 2.4 Sodium citrate has excellent chelating properties and is therefore widely used in the electroplating industry; In the construction industry, sodium citrate can be added as a retarder to concrete to improve the tensile, compressive, and frost resistance of cement products; 2.5 In terms of environmental protection, sodium citrate can be used to remove sulfides from industrial exhaust gas. In the ceramic industry, sodium citrate can be used as a grinding aid additive. In addition, sodium citrate has new applications in the brewing and photography industries, further expanding its application areas. Uses : Blood collection additive Synonyms : no data
