Calcium formate, also known as calcium formate, is a white or beige crystalline powder. Slightly hygroscopicity, neutral non-toxic soluble in water, slightly bitter taste, not flammable and explosive. At present, calcium formate includes calcium formate of industrial grade and calcium formate of feed grade. As a new type of feed additive, feed grade calcium formate is suitable for all kinds of animal feed acidification and anti-mildew agent, which can prevent diarrhea, dysentery and help digestion and absorption.
Formic acid and hydrated lime are neutralized to produce calcium formate, which is refined to produce commercial calcium formate (e.g.
2. Complex decomposition method
In the presence of a catalyst, sodium formate and calcium nitrate were decomposed to produce calcium formate and sodium nitrate. Commercial calcium formate is obtained by refining.
3. By-product method of methyl ester of epoxy fatty acid
At present, the production of methyl ester of epoxy fatty acid is developing rapidly. During the production of this product, a large amount of by-product formic acid will be produced. One of the utilization schemes of this by-product formic acid is the production of calcium formate.
4. Pentaerythritol by-production method
During the production of pentaerythritol, calcium hydroxide was used to provide basic reaction conditions, and calcium formate was produced by adding formic acid and calcium hydroxide during the subsequent neutralization process. The calcium formate obtained by this method was of high quality (e.g. Chifeng ruiyang chemical co., LTD.).
