    • Described is a method of preparing aldehydes, or aldehydes and alcohols, by the hydroformylation of olefins with more than three carbon atoms, the method including a hydroformylation stage in which the olefin is hydroformylated at a pressure of 50 to 1,000 bar and a temperature of 50 to 180 DEG C by means of a rhodium catalyst dissolved in a homogeneous reaction medium and a catalyst-recovery stage in which the rhodium catalyst is extracted using an aqueous solution of a complexing agent, the alcohol and/or alkdehyde is isolated from the extracted hydroformylation products, the aqueous rhodium-containing extract is carbonylated in the presence of carbon monoxide, synthesis gas or a gas mixture containing carbon monoxide at a pressure of 50 to 1,000 bar and a temperature of 50 to 180 DEG C, the carbonylation products separated into an organic phase containing most of the rhodium and an aqueous phase containing the complexing agent and the organic phase is fed back to the hydroformylation stage, the rhodium catalyst obtained from the products of the hydroformylation stage being extracted with an aqueous solution of a water-soluble polymer, without any sulphonic acid groups, capable of forming a complex with rhodium.
    • 一种用于通过具有多于3个碳原子,包括加氢甲酰化步骤的烯烃的加氢甲酰化制备醛或醛和醇的方法,其中一个接的溶解在均相反应介质中的铑催化剂装置,在50至1000巴的烯烃和50至180℃的温度下 加氢甲酰化和催化剂回收步骤由铑催化剂的提取与络合剂的水溶液,从所提取的加氢甲酰化产物的醇和/或醛的分离,在50至1000的压力含有一氧化碳,合成气或一氧化碳气体混合物的存在下在水含铑提取物precarbonylation 巴和温度为50〜180℃时,precarbonylation的排出分离成铑的有机相的含主要部分和含有配位剂和再循环的水相 有机相萃取到加氢甲酰化阶段,其中,所述铑催化剂是从加氢甲酰化的放电能力,具有sulfonsäuregruppenfreien的水溶液,对铑的水溶性聚合物的螯合。
