    • The invention relates to a process for the continuous preparation of aldehydes and/or alcohols having at least 6 carbon atoms by multistage hydroformylation of olefins or olefin mixtures having at least 5 carbon atoms in the presence of unmodified cobalt complexes, in which at least two reactors are operated at different temperatures in the temperature range from 100 to 220° C. and pressures of from 100 to 400 bar, which is characterized in that a) one reactor is operated at temperatures above 160° C. by the one-pot process with simultaneous catalyst formation, catalyst extraction and hydroformylation and the amount of water fed into the reactor with the aqueous cobalt salt solution is greater than that discharged from the reactor with the liquid reaction mixture and the gas phase together, with part of the aqueous bottom phase being discharged from the reactor to keep the level of the aqueous bottom phase constant, b) and the cobalt carbonyls in the aqueous phase taken off or part thereof are introduced into the reactor which is operated at a lower temperature.
    • 本发明涉及通过在未改性的钴配合物存在下,通过使具有至少5个碳原子的烯烃或烯烃混合物进行多级加氢甲酰化,连续制备具有至少6个碳原子的醛和/或醇的方法,其中至少两个反应器 在不同的温度下在100至220℃的温度范围和100-400巴的压力下操作,其特征在于:a)一个反应器在160℃以上的温度下通过一锅法操作, 同时催化剂形成,催化剂萃取和加氢甲酰化反应,并且用钴盐水溶液进料到反应器中的水量大于从反应器排出的水,液体反应混合物和气相在一起,部分水相底部为 从反应器排出以保持水相底部相的水平恒定,b)和水相中的羰基钴脱离或部分t 将其引入在较低温度下操作的反应器中。
