Trisodium citrate, also known as sodium citrate, is an organic compound with white to colorless crystals in appearance. Odorless, cool, salty and spicy. It is stable at room temperature and in the air, slightly soluble in humid air, and weathering in hot air. It loses crystal water when heated to 150℃. It is easily soluble in water, soluble in glycerin, hardly soluble in alcohols and other organic solvents. It decomposes by overheating. It is slightly deliquescence in humid environment and slightly weathered in hot air. The pH value of the solution is about 8.

Trisodium citrate has very good solubility, and the solubility increases with the increase of water temperature. Trisodium citrate is a weak acid and strong base salt. It can be combined with citric acid to form a strong pH buffer. And what are the uses of trisodium citrate?

Uses of trisodium citrate:

1. In terms of food, it is used as a pH regulator and emulsification enhancer. It is mostly used in jams, candies, jellies, etc., and it can alleviate sourness when matched with citric acid. However, because citric acid is always a chemical material, it is stipulated that it needs to be used in an appropriate amount during production.

2. In industry, trisodium citrate can promote biological degradation and dispersion. Trisodium citrate can also be used as a washing agent. It is widely used in washing powder to promote sewage discharge into rivers, alleviate water pollution, and promote algae. Rapid reproduction.

3. In medicine, trisodium citrate is mainly used as an anticoagulant and blood transfusion, prolongs the shelf life of blood products and checks the acidity of urine, a multivalent complexing agent, and a sequestering agent for removing trace metals.

4. Trisodium citrate is used as a preservative to preserve the syrup. When using it, follow the doctor's advice.

The above are some uses of trisodium citrate, and trisodium citrate is widely used in food, industry, medicine and other fields. And the main component of trisodium citrate is citric acid, and citric acid is a natural ingredient, which will not cause harm to the body.

So how is trisodium citrate prepared?

The synthesis method of trisodium citrate is obtained by neutralizing citric acid with hydrogen or sodium bicarbonate. Dissolve sodium bicarbonate in water under stirring and heating, add citric acid, continue to heat up to 85~90℃, adjust pH to 6.8. Add activated carbon to decolor, and filter while hot. The filtrate was concentrated under reduced pressure, and the crystals were picked out after cooling, filtered, washed, and dried to obtain trisodium citrate.
