Hydrogenation of Organic Compounds Containing Sulfur over Co-Mo-Al203 Catalysts

CO Hydrogenation over Alumina-Supported Sulfide Cluster Catalysts

Bimetallic Mo-Fe and Mo-Co sulfide clusters were anchored on AI,O, and used for CO hydrogenation. In addition to methane, significant amounts of dimethyl ether were produced. The reaction orders obtained from power rate laws for methanation indicated that the surfaces of the catalytic ensembles were not completely saturated by CO, in contrast to the observations for most conventional CO hydroge...

Liquid-phase Catalytic Transfer Hydrogenation of Aromatic Nitro Compounds over Nickel-doped Carbon Catalysts

Ni-doped carbon aerogel catalysts were prepared through sol-gel polycondensation of furfural with resorcinol in the presence of nickel nitrate salts, followed by drying at ambient pressure and then carbonization in N2. The catalysts were used for catalytic transfer hydrogenation of aromatic nitro compounds with propan-2-ol as hydrogen donor and KOH as promoter, and have been found to exhibit ex...

ORGANIC CHEMISTRY Organic Compounds containing Nitrogen

Sulfur-containing compounds from Clinacanthus siamensis.

Two new sulfur-containing compounds, trans-3-methylsulfonyl-2-propenol (1) and trans-3-methylsulfinyl-2-propenol (2) were isolated together with trans-3-methylthioacrylamide (3), entadamide A (4) and entadamide C (5) from the leaves of Clinacanthus siamensis. The structures were established on the basis of the spectroscopic data. The compounds were tested for antimalarial and antimycobacterial ...

Ethylene hydrogenation on Mo(CO)6 derived model catalysts in ultrahigh vacuum: From oxycarbide to carbide to MoAl alloy

The ethylene hydrogenation activity is compared for molybdenum oxycarbides, molybdenum carbides and a molybdenum alloy formed by reaction of molybdenum hexacarbonyl with alumina in ultrahigh vacuum using temperature-programmed desorption. It is found that molybdenum oxycarbides are inactive for ethylene hydrogenation. It is shown by forming carbides by reaction between alumina and ethylene that...
