a b s t r a c t 4,4 -Dimethyl-2,2 -bipyridine is a useful but expensive chelating agent. Having more efficient routes to the synthesis of this compound would be advantageous to the wide-spread use of this fine chemical. In this work, the effects of adding strongly interacting oxides (ZnO, CeO 2 , an

The C-H activation and C-C coupling of 4-methyl pyridine to 4,4 -dimethyl-2,2 -bipyridine was studied over palladium catalysts supported on nanoparticle alumina [nano-Al 2 O 3 (+)]. Even though Pd/Al 2 O 3 catalysts are traditionally poor catalysts in this reaction, the Pd/nano-Al 2 O 3 (+) catalyst
The selective oxidation of lactose by molecular oxygen has been studied in a batch reactor containing an aqueous slurry of 0.5 kmol m-1 reactant and 1.0 kg m-3 catalyst. The in situ Bi promotion of a commercial Pd-C catalyst resulted in 100% selectivity to sodium lactobionate up to conversions of 95
Catalytic properties of supported neodymium oxide in oxidative coupling of methane were studied. The most efficient catalysts contain NdzOa as separated phase. The efficiency increases with the rise of oxidative sites concentration in catalyst li?froduition.
