1. A process for preparing aldehydes by the reaction of olefins having 6 to 20 carbon atoms with carbon monoxide and hydrogen in liquid phase in the presence of water, rhodium in metallic form or as a compound and a water-soluble arylphosphine at temperatures of 20 to 150 degrees C and pressures of 1 to 200 bar (100 to 2 X 10**4 kPa), characterised in that the water-soluble phosphine has the general formula : see diagramm : EP0163234,P6,F2 where Ar denotes an aryl group and X a sulfonic acid group, x**1 , x**2 and x**3 are 0 or 1 subject to the condition that at least one number x**1 , x**2 or x**3 is 1, A stands for an alkyl or, aralkyl radical having 7 to 18 carbon atoms and B, C and D are straight-chain or branched alkyl radicals having 1 to 4 carbon atoms and n is an integer between 1 and 3. |
