“…In these cases, the catalyst used was Ag/Al2O3. We also found that H2 addition lowered the decomposition temperature of N,N-dimethylformamide over Pt and Pd catalysts 6) . H2 addition to the feedstock both enhances hydrocarbon conversion and reduces emissions.…”

The effect of H2 addition on hydrocarbon oxidation over Al2O3-supported noble metal catalysts was investigated. CO2 was formed below the light off temperature of olefin combustion by the addition of H2 over Pt and Ir catalysts. Particularly for C2H4 combustion, Pt catalysts exhibited significant CO2 formation at 70 . CO2 formation at low temperature increased with increasing Pt particle size. CO2 formation in the C2H4 O2 H2 reaction at 70 over Pt/Al2O3 decreased with increasing contact time. Pt/Al2O3 showed very high activity for hydrogenation of C2H4 even at room temperature. DRIFTS measurement revealed that ethylidene was formed as an intermediate of the C2H4 H2 reaction, and then consumed by the addition of O2. We conclude that ethylidene intermediates of C2H4 hydrogenation are involved in the low-temperature CO2 formation.

“…Taking into account that DMF can be decomposed into dimethylamine and carbon monoxide in the pres ence of platinum group metal complexes according to published [15][16][17], we studied the reaction of nonene 1 with synthesis gas in a DMF medium without the addition of dimethylamine. Table 6 shows the results obtained using the Rh(acac)(CO) 2 + PPh 3 catalyst sys tem.…”

The hydroaminomethylation of alkenes with dimethylamine catalyzed by rhodium and ruthe nium complexes in a dimethylformamide medium under synthesis gas pressures of 2 MPa has been studied. It has been shown that the combined use of these metals leads to a significant increase in the rate of formation of amines and selectivity for n alkyldimethylamine. It has been found that the reaction can proceed with dim ethylformamide used as an aminating agent without the addition of dimethylamine.
