Sodium citrate is an organic compound with a chemical formula of C6H5Na3O7. It is soluble in water and glycerin, but hardly soluble in ethanol. The aqueous solution is slightly alkaline. It is often used as a buffer, complexing agent, and bacterial culture medium. It is used in medicine for diuresis. , expectorant, sweating, prevent blood coagulation, and for food, beverages, electroplating, photography and other aspects.
1. Food
Sodium citrate is mainly used as a food additive with the largest demand. It can also be used as a flavoring agent, expansion agent, stabilizer, buffer, and emulsifier. In addition, sodium citrate and citric acid can also be used as various Flavoring agents, gelling agents and nutritional supplements for pastries, fruit juices, beverages, cold drinks, dairy products and jams.
2. Medicine
In 1914, sodium citrate was developed as a long-acting anticoagulant, allowing blood to be preserved longer. Sodium citrate also has antiseptic effect and is used to preserve some medicines.
3. Construction Industry
In the construction industry, sodium citrate can be added as a retarder when making concrete, which can improve the antifreeze, compressive and tensile properties of cement products; under the social conditions of increasingly serious environmental problems, the emptying of some smelters Sulfur dioxide in the flue gas seriously exceeds the standard. Studies have shown that the use of sodium citrate's own characteristics to remove sulfides in industrial tail gas has an obvious effect.
4. Electroplating and manufacturing
Because sodium citrate has good complexing properties, it is also used in the electroplating industry. The electroplating process has developed rapidly. Neutral citrate nickel plating has the advantages of environmental protection, pollution-free, easy maintenance, low corrosion, and excellent coating performance, so it has been used on a large scale in industrial production. In addition, sodium citrate is also used in the manufacture of nanomaterials and the grinding aid and whitening technology of the ceramic industry.
5. Industrial cleaning
The properties of sodium citrate can be added to the detergent to improve the decontamination effect, so sodium citrate has been widely used in the manufacture of phosphorus-free washing powder and liquid detergent.
