Abstract: The effect of 1,2-dichloroethane, trichloroethylene, and tetrachloromethane on hydroformylation of propylene (0.596 mole) in toluene at 100 ± 1°C and initial pressure on an equilibrium mixture of carbon monoxide and hydrogen of approx. 13.8 MPa was investigated using řrans-RhCl(CO)(PPh₃)₂ (9.26 x 10^-6 mole) as a catalyst. These additives showed retardation and inhib­itory effects on hydroformylation of propylene and their molar efficiency could be expressed by the following relative numbers: trichloroethylene : 1,2-dichloroethane : tetrachloromethane = 1  3.5  25. Trichloroethylene as well as allyl and vinyl chlorides were practically not hydroformylated even at threefold amount of the catalyst under the above-mentioned conditions.
