Trisodium citrate dihydrate is widely applied in beverages as a buffering, sequestering, or emulsifying agent. It helps to maintain the desired pH levels and improve the stability and quality of the beverages.
Used in Electroplating Industry:
In the electroplating industry, trisodium citrate dihydrate is used as a complexing agent and buffering agent. It helps to improve the efficiency and quality of the electroplating process.
Used in Cleaning Products:
Trisodium citrate dihydrate is used in various cleaning products, such as functional fluids, solvents for cleaning, furnishing care products, laundry and dishwashing products, and cleaning automobile radiators. It acts as a sequestering agent to remove trace metals and improve the cleaning efficiency.
Used in Brewing, Photography, and Newspaper and Movie Chemicals:
Trisodium citrate dihydrate is also used in brewing, photography, and the production of chemicals for newspapers and movies. It serves various functions, such as an emulsifier, acidulant, and sequestrant in these industries.

Excellent performance

Sodium citrate is currently the most important citrate. It is produced by two steps: first starch food is fermented to generate citric acid; secondly, citric acid is neutralized by alkali to generate the final products. Sodium citrate has the following excellent performance: Safe and nontoxic properties; Since the basic raw material for the preparation of sodium citrate mainly comes from the food, it is absolutely safe and reliable without causing harm to human health. The United Nations Food and Agriculture and the World Health Organization has no restriction in its daily intake, which means that this product can be considered as non-toxic food. It is biodegradable. After subjecting to the dilution of a large amount of water, sodium citrate is partially converted into citrate, which coexists with sodium citrate in the same system. Citrate is easy to subject to biological degradation at water by the action of oxygen, heat, light, bacteria and microbes. Its decomposition pathways are generally going through aconitic acid, itaconic acid, citraconic acid anhydride to be further converted to carbon dioxide and water. The ability of forming complex with metal ions. Sodium citrate has a good capability of forming complex with some metal ions such as Ca2+, Mg2+; for other ions such as Fe2+, it also has a good complex-forming ability. Excellent solubility, and the solubility increases with increasing temperature of water. It has a good capability for pH adjustment and a good buffering property. Sodium citrate is a weak acid-strong alkali salt; When combined with citrate, they can form a pH buffer with strong compatibility; therefore, this is very useful for some cases in which it is not suitable to have large change of pH value. In addition, sodium citrate also has excellent retardation performance and stability. The above information is edited by the lookchem of Dai xiongfeng.

Effect and application

During the process of clinically taking fresh blood, adding some amount of sterile sodium citrate can play a role in prevent blood clotting; this is exactly taking advantage of the features that calcium citrate can form soluble complexes with calcium ion; In the field of medicine, it is used for the in vitro anti-clotting drugs and anticoagulants drugs, phlegm drugs, and diuretics drugs during blood transfusions; it can also used for cyanide-free electroplating industry; also used as developer for photographic industry. It can be used as flavoring agents, buffering materials, emulsifiers, and stabilizer in the food industry. Moreover, it is also widely used in chemical, metallurgical industry, the absorption of sulfur dioxide exhaust with the absorption rate of 99% and regenerate liquid sulfur dioxide citrate for recycle application. Sodium citrate has a good water solubility and a excellent cheating capability with Ca2 +, Mg2 + and other metal ions; it is biodegradable and has a strong dispersing ability and anti-redeposition ability; Daily-applied chemical detergents use it as alternative to trimer sodium phosphate for production of non-phosphorus detergent and phosphate-free liquid detergent. Adding a certain amount sodium citrate to the detergent can significantly increase the cleaning ability of detergent cleaning. The large scale of application of sodium tripolyphosphate as a builder in detergents is an important discovery in synthetic detergent industry. It is non-toxic without environmental pollution; it can also be acted as a buffer for the production of cosmetics.

Production methods

It is produced by the neutralization of citric acid by sodium hydroxide or sodium bicarbonate. Dissolve sodium bicarbonate in water upon stirring and heating; add citric acid, continue to heat up to 85-90 °C; adjust the pH to 6.8; adjust active carbon for bleaching. Filter when the mixture is still hot; condense the filtrate under reduced pressure; cool and the crystal comes out; filter, wash, dry to obtain the final products of sodium citrate. C6H8O7 + 3NaHCO3 → C6H5Na3O7 ? 2H2O + 3CO2 ↑ + H2O

Production Methods

Sodium citrate is prepared by adding sodium carbonate to a solution of citric acid until effervescence ceases. The resulting solution is filtered and evaporated to dryness.

Pharmaceutical Applications

Sodium citrate, as either the dihydrate or anhydrous material, is widely used in pharmaceutical formulations. It is used in food products, primarily to adjust the pH of solutions. It is also used as a sequestering agent. The anhydrous material is used in effervescent tablet formulations. Sodium citrate is additionally used as a blood anticoagulant either alone or in combination with other citrates such as disodium hydrogen citrate. Therapeutically, sodium citrate is used to relieve the painful irritation caused by cystitis, and also to treat dehydration and acidosis due to diarrhea.

Biochem/physiol Actions

Sodium citrate can act as a buffering agent, resisting changes in pH. Used in blood collection tubes, the citrate chelates calcium ions in blood and thereby disrupts blood clotting. Citrate is a intermediate in the TCA cycle and fatty acid synthesis. Citrate is an allosteric modulator of acetyl-CoA carboxylase, the enzyme that regulates the conversion of acetyl-CoA to malonyl-CoA.

Safety

After ingestion, sodium citrate is absorbed and metabolized to bicarbonate. Although it is generally regarded as a nontoxic and nonirritant excipient, excessive consumption may cause gastrointestinal discomfort or diarrhea. Therapeutically, in adults, up to 15 g daily of sodium citrate dihydrate may be administered orally, in divided doses, as an aqueous solution to relieve the painful irritation caused by cystitis. Citrates and citric acid enhance intestinal aluminum absorption in renal patients, which may lead to increased, harmful serum aluminum levels. It has therefore been suggested that patients with renal failure taking aluminum compounds to control phosphate absorption should not be prescribed citrate- or citric acid-containing products.

storage

Sodium citrate dihydrate is a stable material. Aqueous solutions may be sterilized by autoclaving. On storage, aqueous solutions may cause the separation of small, solid particles from glass containers. The bulk material should be stored in an airtight container in a cool, dry place.

Incompatibilities

Aqueous solutions are slightly alkaline and will react with acidic substances. Alkaloidal salts may be precipitated from their aqueous or hydro-alcohol solutions. Calcium and strontium salts will cause precipitation of the corresponding citrates. Other incompatibilities include bases, reducing agents, and oxidizing agents.

Check Digit Verification of cas no

The CAS Registry Mumber 6132-04-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,3 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6132-04:
(6*6)+(5*1)+(4*3)+(3*2)+(2*0)+(1*4)=63
63 % 10 = 3
So 6132-04-3 is a valid CAS Registry Number.

Method for the preparation and recovery of alkali metal citrates

-

, (2008/06/13)

Alkali metal citrates are prepared by the addition of an alkaline alkali metal base or salt to citric acid solutions and recovered in solid form by the addition of a C1 to C5 alcohol to the solution to cause precipitation.
