Calcium Acetate, with the chemical formula Ca(CH3COO)2 or C4H6CaO4, is a chemical compound that has found widespread utility across diverse sectors. Understanding its fundamental chemical properties, including its synthesis and physical characteristics, is key to appreciating its broad applicability. NINGBO INNO PHARMCHEM CO.,LTD. specializes in producing high-purity Calcium Acetate, ensuring it meets the stringent requirements for its various applications.

Calcium Acetate typically appears as a white, crystalline solid or powder. The anhydrous form is notably hygroscopic, meaning it readily absorbs moisture from the atmosphere, which is why the monohydrate form, Ca(CH3COO)2•H2O, is more commonly encountered. It possesses a slight acetic acid odor due to residual acetic acid content. In terms of solubility, Calcium Acetate is soluble in water, which is a critical property for its use in aqueous solutions and formulations. It is also slightly soluble in methanol but generally insoluble in ethanol, acetone, and benzene.

The synthesis of Calcium Acetate can be achieved through a straightforward reaction between calcium carbonate (CaCO3) or calcium hydroxide (Ca(OH)2) and acetic acid (CH3COOH). A common method involves reacting calcium carbonate, such as that found in limestone or eggshells, with acetic acid. The reaction produces calcium acetate in aqueous solution, along with carbon dioxide and water. The equation for this reaction is: CaCO3(s) + 2CH3COOH(aq) → Ca(CH3COO)2(aq) + H2O(l) + CO2(g).

Industrially, Calcium Acetate's properties are leveraged in various ways. Its ability to chelate metals makes it useful in water treatment for removing heavy metals. In lubricants, it acts as a thickening agent. Historically, it was a common starting material for acetone production via thermal decomposition. The compound's melting point is around 160 °C, at which point it begins to decompose. The detailed chemical and physical properties of Calcium Acetate, coupled with its relatively simple synthesis, contribute to its value as a versatile chemical intermediate and functional ingredient. NINGBO INNO PHARMCHEM CO.,LTD. ensures that its production processes yield a product with consistent chemical integrity, meeting the needs of pharmaceutical, food, and industrial clients.
