    摘要: The invention relates to a method for producing tricyclodecandialdehyde by hydroformulating dicyclopentadiene by means of a CO/H2-mixture in the presence of a non-ligand modified rhodium catalyst which can be dissolved in a homogenous manner in the hydroformulation medium at a high temperature and at high pressure. Hydroformulation is carried out at pressure of between 200 - 350 bar in at least two reaction zones. In a first reaction zone, the reaction temperature is adjusted from 80 to 120 °C and in a reaction zone, which follows on from the latter, the temperature is adjusted from 120 to 150 °C, with the proviso that the reaction temperature in the subsequent reaction area is at least 5 °C higher that in the previous reaction zone.
