PROCESS FOR THE PREPARATION OF FORMIC ACID BY REACTING CARBON DIOXIDE WITH HYDROGEN

摘要

Process for the preparation of formic acid by reacting carbon dioxide with hydrogen in a hydrogenation reactor in the presence of a catalyst comprising an element from the 8th, 9th or 10th group of the Periodic Table of the Elements, of a tertiary amine and of a polar solvent, with formation of formic acid-amine adducts, which are then cleaved thermally to give formic acid and tertiary amine.
