METHOD FOR PRODUCING ALKANALS USING A RHODIUM-TRI-POLYETHYLENE GLYCOLATE |
摘要 |
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° 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. |
