Reaction Conditions

Reaction Steps

Into an autoclave are charged 294.6 g (=420 ml, 3 moles) of heptene-3, 50 ppm of Rh (based on heptene-3) in the form of RhCl3, and 2.8 g of tributyl phosphine (molar ratio of Rh:phosphine=1:100). A pressure of 150 bars is adjusted by introducing CO and H2 (molar ratio, 1:1). Thereafter, the temperature is increased to 130° C. and the pressure to 290 bars. After 3 hours, the olefin is reacted quantitatively. As is shown by the analysis by gas chromatography, the reaction product contains 2-propyl pentanal and 2-ethyl hexanal in a ratio of about 75:25. The yield (2-propyl pentanal+2-ethyl hexanal) is 346 g. The hydroformylation product is directly oxidized after flash distillation.
