What is the production method of calcium formate?

1、中和法

1. Neutralization method

甲酸与熟石灰中和生成甲酸钙，经精制而得商品甲酸钙

Calcium formate is produced by neutralization of formic acid and hydrated lime and refined to produce commercial calcium formate 

2、复分解法

2. Double decomposition method

甲酸钠与硝酸钙在催化剂存在下发生复分解反应得到甲酸钙，联产硝酸钠。经过精制得到商品甲酸钙。

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、环氧脂肪酸甲酯副产法

3. By product method of epoxy fatty acid methyl ester

目前环氧脂肪酸甲酯生产发展较快，这个产品生产过程中会产生大量副产的甲酸，这种副产的甲酸一种利用方案就是生产甲酸钙。

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、季戊四醇副产法

4. Pentaerythritol by-product method

季戊四醇生产过程中利用氢氧化钙提供碱性反应条件，在反应的后续加入甲酸与氢氧化钙中和过程的同时副产甲酸钙，该法所得甲酸钙品质较高。

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.
