<p>The catalytic activity of Rh-Co-phosphine complexes for hydroformylation of propene≮e.g., HRh(CO)(PPh3)-PPh3≉ws stabilized and / or regenerated by addn. of Co, e.g., CO2(CO)8 Pr Co(OAc)2. Thus, n-butylaldehyde 20cm3, Rhodium trisfydridocarbonyl triphenyl phosphine, HRhCO(Pφ3)3 43 mg and triphenyl phosphine,φ3P 1.33 g were added in autoclave 200ml and made air-tight, stirred and heated to 125≰C for 90 min. A reactive mixed gas, whose mixing ratio of CO/H2/propene was 1/1/1, was continuously added and pressure kept at 12.1 bar to give the reduction of catalytic activity, 27 %.</p> |
