Hydrogenolysis of methyl linoleate over oxide catalyst derived from Mg2Cu alloy.

Understanding the Reaction Mechanism of Glycerol Hydrogenolysis over a CuCr2 O4 Catalyst.

The reaction mechanism of glycerol hydrogenolysis to 1,2-propanediol over a spinel CuCr2 O4 catalyst was investigated by using DFT calculations. Theoretical models were developed from the results of experimental characterization. Adsorption configurations and energetics of the reactant, intermediates, final product, and transition states were calculated on Cu(1 1 1) and CuCr2 O4 (1 0 0). Based ...

Efficient Hydrogenolysis of Guaiacol over Highly Dispersed Ni/MCM-41 Catalyst Combined with HZSM-5

A series of MCM-41 supported Ni catalysts with high metal dispersion was successfully synthesized by simple co-impregnation using proper ethylene glycol (EG). The acquired Ni-based catalysts performed the outstanding hydrogenolysis activity of guaiacol. The effects of the synthesis parameters including drying temperature, calcination temperature, and metal loading on the physical properties of ...

Characterization by NMR of Ozonized Methyl Linoleate

No presente estudo o linoleato de metila ozonizado com índice de peróxidos de 1.800 mmol-equiv. kg foi caracterizado quimicamente. Os efeitos do ozônio sobre o linoleato de metila produz hidroperóxidos, ozonideos e aldeídos, os quais foram identificados por técnicas de ressonância magnética nuclear de H e C, monoe bidimensional. O linoleato de metila padrão e o linoleato de metila ozonizado mos...

Abatement of Benzyl Alcohol and Methyl Ethyl Ketone (MEK) from Polluted Air Over Nanostructured Mn -Supported Alumina Catalyst

Boryl-assisted hydrogenolysis of a nickel-methyl bond.

A stable nickel(II) methyl complex containing a diphosphino-boryl (PBP) pincer ligand is described. Mechanistic studies on the hydrogenolysis of the Ni-Me bond suggest a metal ligand cooperation mechanism that involves the intermediacy of a σ-B-H Ni(0) species that further undergoes B-H oxidative addition to form a Ni(II) hydride complex.
