PROBLEM TO BE SOLVED: To provide a method for producing an aldehyde which is excellent in yield, selectivity and separation of a reaction product. SOLUTION: Rhodium and formula (I) Wherein R 1 is H or an alkyl group, and R 2 is a linear alkylene group, an oxygen-containing alkylene group, a compound of the formula (II) or (II I) A group or cycloalkylene group, R 3 is an alkyl group or an aryl group, A is -COO - or -SO 3 - And x = 0 and y = 1 and m = 1 and n = 1 or x = 1 and y = 1 and m = (1 or 2) and n = (1 or 2), or R 2 Is a group of formula (II) or (III), x = 1 and y = 0 and m = (0 or 1) and n = (0 or 1)] or a catalyst consisting of a mixture of these compounds, at a temperature of 50-190 ° C. and 0.1-45. At a pressure of MPa, in the presence or absence of a solvent, Reacting the olefinic compound with carbon monoxide and hydrogen, A method for producing an aldehyde, comprising separating a reaction product from a catalyst. |
