At NINGBO INNO PHARMCHEM CO.,LTD., we believe in providing our clients with not just products, but also a deep understanding of their chemistry and manufacturing. Calcium Formate (Ca(HCOO)₂), a vital chemical compound, is produced through specific industrial processes that ensure its quality and suitability for diverse applications, ranging from construction to animal feed. Understanding its properties and manufacturing is key to leveraging its full potential.

The most common industrial method for producing Calcium Formate involves the reaction between calcium hydroxide (Ca(OH)₂) and formic acid (HCOOH). This reaction is straightforward, typically carried out at room temperature and atmospheric pressure, yielding Calcium Formate and water: Ca(OH)₂ + 2HCOOH → Ca(HCOO)₂ + 2H₂O. The resulting Calcium Formate is then separated, dried, and milled into a fine powder. This process is highly controllable, allowing for the production of high-purity Calcium Formate suitable for demanding applications. The neutralization method is generally preferred for feed-grade Calcium Formate to ensure low levels of heavy metals and other impurities.

Alternatively, Calcium Formate can be produced as a co-product in certain chemical manufacturing processes, such as the production of trimethylolpropane. In these scenarios, hydrated lime is used, and the Calcium Formate is separated and purified. Other less common methods include reacting calcium hydroxide with carbon monoxide at elevated temperatures and pressures or reacting calcium chloride with formic acid.

The physical and chemical properties of Calcium Formate are central to its widespread use. It typically appears as a white, crystalline powder with a slightly acidic odor. Its solubility in water is notable, though it changes with temperature, being higher at warmer temperatures. For instance, at 0°C, its solubility is about 16.1 g/100 g of water, while at 100°C, it increases to 18.4 g/100 g. This solubility is critical for its application in aqueous solutions, such as concrete admixtures or tanning liquors. Calcium Formate is stable at room temperature, making it easy to store and handle.

Another important characteristic is its thermal stability. Calcium Formate decomposes at high temperatures, typically above 300°C, which is beneficial in processes like feed pelletizing where additives can be exposed to heat. The formulation of Calcium Formate for specific uses involves careful consideration of particle size, purity, and concentration. For example, feed-grade Calcium Formate must meet strict standards regarding heavy metal content to ensure animal safety. Similarly, construction-grade Calcium Formate is optimized for particle size and reactivity to achieve the desired acceleration effects in cementitious materials.

At NINGBO INNO PHARMCHEM CO.,LTD., we ensure that our Calcium Formate products are manufactured with precision, adhering to international quality standards. This commitment to quality manufacturing allows our customers to confidently utilize Calcium Formate for its intended purposes, whether that’s accelerating concrete cure times, preserving animal feed, or enhancing leather tanning processes.
