용도
개요
Calcium acetate is a chemical compound which is calcium salt of acetic acid. It has the formula Ca(C2H3O2)2. Its standard name is calcium acetate, while calcium ethanoate is the systematic name. An older name is acetate of lime. The anhydrous form is very hygroscopic; therefore the monohydrate (Ca(CH3COO)2H2O) is the common form.
용도
Calcium Acetate is the calcium salt of acetic acid which functions as a sequestrant and mold control agent. it contains approximately 25% calcium. it is a white odorless powder which is readily soluble in water with a solubility of approximately 37 g in 100 g water at 0°c. its solubility decreases with increasing temperature, with a sol- ubility of approximately 29 g in 100 g of water at 100°c.
일반 설명
Calcium Acetate belongs to the group of calcium salts, widely used as phosphorus binders in patients with chronic renal failure.Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
제조 및 합성 방법
생산 방법
Calcium acetate can be prepared by soaking calcium carbonate (found in eggshells, or in common carbonate rocks such as lime stone or marble) in vinegar: CaCO3 + 2CH3COOH → Ca(CH3COO)2 + H2O + CO2 Since both reagents would have been available pre-historically, the chemical would have been observable as crystals then.
제조 방법
Produced by calcium hydroxide neutralization of acetic acid.
