The invention is a process for production of C3 to C6 aldehydes by hydroformylating a mixture containing: (a) C2 to C5 olefins and mixtures thereof, and (b) (i) C2 to C5 alkynes and mixtures thereof or (ii) C3 to C5 cumulated dienes and mixtures thereof or (iii) mixtures of (i) and (ii), with CO, H2

The invention is a process for production of C3 to C6 aldehydes by hydroformylating a mixture containing: (a) C2 to C5 olefins and mixtures thereof, and (b) (i) C2 to C5 alkynes and mixtures thereof or (ii) C3 to C5 cumulated dienes and mixtures thereof or (iii) mixtures of (i) and (ii), with CO, H2 and a solution of a rhodium complex catalyst produced by complexing Rh and an organophosphorus compound at a concentration of Rh in solution from 1 to 1000 ppm by weight. Alternatively, the solution of rhodium complex catalyst can have a P/Rh atom ratio of at least 30. Alternatively, the solution of rhodium complex catalyst can have a P/Rh atom ratio greater than the value RL defined by the formula: [Figure] in which RB is the P/Rh ratio sufficient for a catalytically active Rh complex, pKaTPP is the pKa value for triphenylphosphine, pKaL is the pKa value for the triorganophosphorus compound, R is the gas constant, and DB is 35(N-1) cal/mole/°K., N is the number of P-Rh attachments per ligand molecule. The process has utility for the hydroformylation of streams that contain olefins and alkynes.
