To provide a production process for carbonyl compound that can recover the noble metal complex as a rhodium complex in no need of precipitation of the complex, after the reaction mixture tentatively is taken out from the reactor in order to separate and recover the carbonyl compound from the reaction mixture including a noble metal complex as a rhodium complex.
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 following two steps are provided: the first one where the reaction mixture taken out of the reactor 1 is pressure-released and the second one following the pressure release where a gas containing carbon monoxide is fed to the feed line toward the separation column are provided.
