Selenium Dehydrogenation of Thujopsene.

Dehydrogenation of Benzene on Liquid

The reactions of benzene on Al100 + have been investigated as a function of cluster temperature (300−1100 K) and relative kinetic energy (1−14 eV) by low-energy ion-beam methods and mass spectrometry. Benzene chemisorbs on both solid and liquid aluminum clusters to generate Al100C6D6 . A series of Al100−n + (n = 1, 2, 3, ...) products was also observed. As the cluster temperature was raised abo...

Dehydrogenation by Heterogeneous Catalysts

The protective effect of selenium nanoparticles and selenium against paracetamol

Objective(s): Nanotechnology has enabled researchers to synthesize nanosize particles that possess increased surface areas. Compared to conventional microparticles, it has resulted in increased interactions with biological targets.The objective of this study was to determine the protective ability of selenium nanoparticles compared to selenium against parasetamol hepatotoxicity and GPX concentr...

Pyridine Hydrogenation and Piperidine Dehydrogenation

The dehydrogenation of piperidine has been studied and found to have an order of -1.5 with respect to the hydrogen partial pressure. By combining these results with those obtained for pyridine hydrogenation on the same catalyst a complete rate equation for piperidine dehydrogenation together with the stoichiometric number of the rate-determining step of these reactions could be derived. This nu...

Dehydrogenation Mechanism in Flavoprotein Catalysis

I "C -X-H+Acc(ox)--> C =X+Acc(red)H 2 I / H This type of reaction should be differentiated from the oxygenase reaction, in which the substrate electrons are transferred directly to oxygen. The limiting chemical step of the dehydrogenation, i.e., the rupture of the kinetically stable substrate C-H bond, is catalyzed by enzymes which have either pyridine nucleotide, pyridoxal-phosphate, flavin-, ...
