Abrégé
(EN)
According to the invention, branched and straight chain alkenes and cycloalkenes with five and more C-atoms are by means of hydroformylation using a novel rhodium-tri-polyethylene glycolate of a polyethylene glycol with an average molecular weight of 320 to 650 as a catalyst with at hydrogen/carbon monoxide pressure of 60 to 200 bar and at a temperature of between 50 and 150 DEG C. converted into branched and straight chain alkanals and cycloalkanals with six and more C-atoms. The reaction is preferably carried out in water or polyethylene glycol or a mixture of the same as a solvent in the heterogeneous phase. The aldehydes obtained are easy to separate from the catalyst in the reaction preparation. Said aldehydes are also obtained with a high level of purity and a high yield.

根据本发明,具有5个或更多碳原子的支链和直链烯烃和环状烯烃,通过用平均分子量为320至650的聚乙二醇的新三(聚乙二醇)铑作催化剂,在氢气/一氧化碳压力为60至200巴,在50至150℃的温度下加氢甲酰化,转化为具有6个和更多碳原子的支链和直链烷醛和环状烷醛。反应优选地在作为溶剂的水或聚乙二醇或其混合物中以多相进行。所得的醛容易与反应混合物中的催化剂分离。所说的醛也以高纯度和高产率得到。
