개요Sodium phosphate dibasic is highly hygroscopic and water soluble. Useful in conjunction with Sodium Phosphate, Monobasic in the preparation of biological buffers. It is commonly used in biological assay buffers. Sodium is required for nerve and muscle functioning. Sodium Phosphate Dibasic can be used as a dietary supplement and as a nutrient. Sodium hydrogen phosphate is used in food and water treatment in conjunction with trisodium phosphate.In foods, it is used to adjust pH. In water treatment, It retards calcium scale formation. It is also found in some detergents and cleaning agents. This product is known to be Used in many applications including the purification of antibodies. It is used as a saline laxative to treat constipation or to clean the bowel before a colonoscopy.
출처Disodium phosphate is anhydrous or contains two molecules of water of hydration
용도Sodium Phosphate, Dibasic is used as a laboratory reagent and a buffer in chemical analysis. Other uses are in manufacturing ceramics, detergents, and enamels; as a mordant in dyeing; for fireproofing paper and wood; for weighting and printing silk; in the treatment of boiler water; as a sequestrant in food; as a dietary supplement; in soldering enamels; and in fertilizers. It is used therapeutically as a cathartic.
일반 설명Sodium phosphate dibasic in combination with sodium phosphate monobasic is used in the preparation of oral sodium phosphate solution (OSPS), which is a purgative used for bowel cleansing before colonoscopy.
제조 방법
Dibasic sodium phosphate is prepared by treating phosphoric acid with a slight excess of sodium carbonate. The solution is boiled to expel carbon dioxide. Upon cooling dodecahydrate crystallizes out. Heating dodecahydrate at 100°C forms the anhydrous salt. H3PO4 + Na2CO3 → Na2HPO4 + CO2 + H2O Dibasic sodium phosphate also is prepared by reacting dibasic calcium phosphate with sodium carbonate. The product calcium carbonate precipitates leaving dibasic sodium salt in the solution. The solution on cooling yields crystals of hydrated product. CaHPO4 + Na2CO3 → CaCO3 + Na2HPO4
