Summary:The invention relates to a process for the hydroformylation of an addition reaction of 1-olefins with hydrogen and carbon monoxide over a rhodium-containing complex catalyst comprising a mixture of phosphorus-containing organic complex ligands, in which the reaction is carried out in a solvent selected from the group of solvents having boiling points greater than or equal to 180 DEG C and less than or equal to 250 DEG C, a catalyst complex having at least two different complex ligands selected from the group consisting of arylphosphines or cycloalkylphosphines is carried out under conditions that the rhodium concentration is greater than or equal to 50 ppm and less than or equal to 250 ppm. The invention also relates to the use of the method according to the invention in the context of a cascade of two-step hydroformylation reactions. 本发明涉及一种用于在含铑络合物催化剂上进行1-烯烃与氢气和一氧化碳的加成反应的加氢甲酰化的方法，该催化剂包含含磷有机络合物配体的混合物，其中，反应在选自沸点大于或等于180℃且小于或等于250℃的溶剂组的溶剂中，具有至少两种不同的选自由芳基膦或环烷基膦组成的组的络合物配体的催化剂络合物具有的铑浓度大于或等于50ppm且小于或等于250ppm的条件下进行
