METHOD FOR PRODUCING ALDEHYDE COMPOUND

摘要

This method for producing an aldehyde compound comprises a step for reacting a compound represented by general formula (a1) or general formula (a2) with hydrogen and carbon monoxide in the presence of a phosphorus compound and a metal compound that contains 0.01-10 ppm by mole of a group 8-10 metal per 1 mole of the compound represented by general formula (a1) or general formula (a2). In this step, the chlorine content in the reaction system is 1.5 parts by weight or less per 1 part by weight of the group 8-10 metal.
