Potassium citrate, also known as potassium citrate, tripotassium citrate.Molecular formula: K3C6H5O7·H2O, molecular weight: 324.4, properties: colorless crystal or white crystalline powder, slightly hygroscopic, easily soluble in water, slowly soluble in glycerol, insoluble in alcohol, taste Salty and cool.Specific gravity: 1.98, use: mainly used as analytical reagents, food additives, alkaline potassium salts in the pharmaceutical industry, used for hypokalemia and alkalized urine, can also be made into high-efficiency compound fertilizers, and can also be used in papermaking , Gold plating and other industries.
Traits
White crystalline granules or crystalline powder, odorless, cool, salty, easily deliquescent, soluble in water and sweet (1g/0.5ml water).The relative density is 1.98, and it melts and decomposes when heated to 230°C.
The main purpose
In the food industry, it is used as a buffer, chelating agent, stabilizer, antioxidant, emulsifier, flavoring agent, etc.It can be used for milk and dairy products, jelly, jam, meat, canned hydrogel snacks, emulsification of cheese, preservation of citrus, etc. It can be used for hypokalemia and potassium deficiency and alkalization of urine in the pharmaceutical industry.It can also be made into high-efficiency compound fertilizer, and can also be used in papermaking, gold plating and other industries.
Urinary stone prevention medicine
Potassium citrate is a commonly used medicine for preventing calculi. Studies have found that the pH value and citric acid value in urine are closely related to the formation of urinary tract calculi.In acidic urine (pH<5.5), the solubility of uric acid is extremely low, and it is easy to cause uric acid stones; in alkaline urine (pH>7), it is very easy to form calcium phosphate or magnesium phosphate stones.63% of patients with urinary tract stones have lower than normal levels of citric acid in their urine, and potassium citrate can provide a large amount of citric acid to increase the pH value in urine, so for uric acid stones, low calcium citrate stones and renal tubular toxicity The calcium stone disease caused by it has a very significant therapeutic effect.But this will result in an increase in potassium ions and a decrease in ammonia ions in the urine, because potassium citrate not only supplements citric acid, but also supplements potassium.Due to the rapid metabolism of potassium in the body, the potassium content in the blood does not change, so it has little effect on the body.From the test of daily total urine volume, oxalic acid, phosphate, sodium, magnesium, sulfate and uric acid in patients with uric acid stones, it was found that potassium citrate was not affected.
