1. Neutralization method
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.
