摘要:
The invention concerns a process for preparing aldehydes by reacting with hydrogen and carbon monoxide at a temperature of between 20 and 170° C. and a pressure of between 1 and 300 bar an olefinically unsaturated C6-C16 compound in the presence aqueous phase containing rhodium and sulphonated triarylphosphines as catalyst and between 10 and 70 wt % of a compound of formula (1), R(OCH2CH2)nOR1, R standing for hydrogen, a straight-chain or branched C1-C4 alkyl group or a C1-C4 hydroxyalkyl group, R1 standing for hydrogen or a methyl group, and n standing for an integer from 3 to 50.
