function | calcium acetate is soluble in water, absorbed in the small intestine and enters the relevant parts of the human body, thus playing the role of calcium. Moreover, since calcium ions in calcium acetate combine with phosphate ions or hydrogen phosphate ions in food, calcium phosphate or calcium hydrogen phosphate that is not easily absorbed by the human body will be generated and discharged from the body, therefore, it can be combined with excessive phosphate in the body, so as to avoid excessive blood phosphorus. In recent years, it has also been used as the first choice for the treatment of hyperphosphatemia. |
preparation | a. The anhydrous calcium acetate was added to the calcium acetate aqueous solution, and the mixture was obtained by stirring while adding, and then the mixture was maintained at 20 ° C., and the stirring was continued for 5H; Wherein, the solid-liquid ratio of the calcium acetate aqueous solution was 0.1g/mL,pH 4; B. The material obtained in Step a is subjected to Suction filtration until the filtrate cannot be filtered out; c. The filter cake obtained in Step B was naturally dried to a constant weight at 18 ° C. And 45%RH, wherein the constant weight condition was a weight difference of 0.2mg. Its purity was 95.6. |
