Title:
METHOD FOR PRODUCING FORMIC ACID SALT, AND METHOD FOR PRODUCING FORMIC ACID.
Document Type and Number:
WIPO Patent Application WO/2023/163014
Kind Code:
A1
Abstract:
The present invention provides a method for producing a formic acid salt, which is suitable for improving the TON of a metal catalyst. This production method is for producing a formic acid salt by reacting hydrogen with a compound C that contains at least one type selected from the group consisting of carbon dioxide, a bicarbonate and a carbonate, such reaction being in the presence of a solvent and using a metal catalyst. The solvent includes an organic solvent and an aqueous solvent. If necessary, a ligand is added to the solvent. The reaction between hydrogen and compound C is carried out in a two-phase system in which the organic solvent is separated from the aqueous solvent and under conditions whereby the value of y, which is calculated from formula (I), is greater than 5.2. y=0.00398×1+(-0.0598)×2+(-15.1)×3+6.66×4+(-0.00340)×5+(-15799)×6+3.43×10-8×7+4.97 (I)
