What is the production method of calcium formate?
1. Neutralization method
Calcium formate is produced by neutralization of formic acid and hydrated lime and refined to produce commercial calcium formate
2. Double decomposition method
Sodium formate reacts with calcium nitrate in the presence of catalyst to produce calcium formate and sodium nitrate. Commercial calcium formate was obtained by refining.
3. By product method of epoxy fatty acid methyl ester
At present, the production of epoxy fatty acid methyl ester is developing rapidly, and a large number of by-product formic acid will be produced in the production process of this product. One utilization scheme of this by-product formic acid is to produce calcium formate.
4. Pentaerythritol by-product method
In the process of pentaerythritol production, calcium hydroxide is used to provide basic reaction conditions. Formic acid and calcium hydroxide are added to neutralize the reaction and calcium formate is produced as by-product. The quality of calcium formate obtained by this method is high.
