Technical Document

Brief Overview

Trisodium citrate anhydrous, also known as sodium citrate, is an inorganic compound represented by the chemical formula Na3C6H5O7. It possesses a saline taste and a mildly tart flavor, often referred to as "sour salt." As the natural tribasic salt of citric acid, its IUPAC name is trisodium;2-hydroxypropane-1,2,3-tricarboxylate. This anhydrous form of trisodium citrate is observed in the form of white, granular crystals or a white, crystalline powder. It exhibits complete solubility in water and is nearly insoluble in ethanol (96%). As a non-toxic and neutral salt with low reactivity, it remains chemically stable when stored at room temperature. Trisodium citrate anhydrous is fully biodegradable and can be disposed of through regular waste or sewage channels

Manufacturing Process

The production of trisodium citrate anhydrous involves dehydrating trisodium citrate dihydrate. This dehydration process eliminates water molecules while preserving the initial crystal matrix. The outcome is the creation of crystals characterized by a porous matrix, enabling them to serve as carriers for both organic and inorganic substances, making them suitable for various applications, including perfumes.

Food Industry

Trisodium citrate anhydrous is predominantly employed as a food additive to enhance flavor and serve as a preservative. Its widespread application as a flavoring agent is evident in club sodas, ready-to-drink beverages, and drink mixes. Additionally, it functions as a buffer, contributing to the regulation of acidity and the prevention of pH fluctuations in various food products like gelatin desserts and milk.

Medical Industry

Trisodium citrate anhydrous finds application as an anticoagulant in blood transfusions, blood collection tubes, and the preservation of blood stored in blood banks. Additionally, it serves as an osmotic laxative and antacid. Its versatile uses extend to alleviating discomfort in urinary tract infections and mitigating acidosis in distal renal tubular acidosis.

Other Applications

Trisodium citrate anhydrous is employed in boiler descaling to efficiently eliminate carbonate scale from boilers without the need for removal during operation. It is also utilized in cleaning automobile radiators.
