PRODUCTION OF CARBONYL COMPOUND

摘要

PROBLEM TO BE SOLVED: To provide a production process for carbonyl compound that can suppress the decomposition rate of the pyridine compound in the catalyst resin and can inhibit liberation of the noble metal supported by catalyst. SOLUTION: A solid catalyst for carbonylation reaction that is composed of a resin having a porous crosslinked structure bearing pyridine rings supporting a noble metal complex thereon is used to carbonylate at least one selected from alcohols, ethers and olefins with carbon monoxide. In this process, the pyridine compound is controlled so as to become 0.5-200wt.ppm in the solution in the carbonylation reactor calculated as the nitrogen concentration.
