MANUFACTURING METHOD AND MANUFACTURING APPARATUS FOR CALCIUM FORMATE

WIPO Patent Application WO/2022/114794

A1

The present invention relates to a manufacturing method and a manufacturing apparatus for calcium formate and, more particularly, to a manufacturing method and a manufacturing apparatus for calcium formate, wherein the formic acid-amine adduct prepared in a process using hydrogenation of carbon dioxide is reacted with a calcium compound, whereby calcium formate can be manufactured and separated in a simple process while excluding complicated separation processes and co-bases required by conventional formic acid manufacturing processes, with the resultant improvement of economical benefit and efficacy in the process.
