The effects of Zn powder, developing agent, temperature of catalyst preparation and reaction conditions such as solvent and pressure on the catalyst activity were studied.

The investigated carbons acted as a catalyst of H1O 2 decom-position and having activities much increased by activation either with ZnCl2 or steam and also by exposure to γ-irradiation. The conditions for the in-situ production of H2 using the mixture NaH2PO2/H3PO2 were studied. Intermediates are formed from DNT through three parallel reactions.

When the addition of La was 0.6%, Ni-La-B catalyst exhibited the highest performance for low-pressure (1 MPa) DNT hydrogenation, the conversion of DNT and selectivity for DAT reached 100%.,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, )—was the most abundant at the higher temperature.

The dispersion of Pd nanoparticles on carbon was measured on the basis of CO adsorption capacity using a pulse technique. For the five identified main reactions, the quantitative kinetic data will be given in another article. The phytoflagellate Ochromonas danica (Chrysophyceae) was grown on a defined medium at low temperatures (15–18°C) and at high temperatures (35.5–37°C), and their sterol content was determined.2.2. Christian H. Hornung, Bart Hallmark, Malcolm R. Mackley, Ian R. Baxendale, Steven V. Ley. ChemInform Abstract: Pd—C-Induced Catalytic Transfer Hydrogenation with Triethylsilane.. Palladium On Carbon (Pd/C) In a blatant plug for the Reagent Guide and the Reagents App for iPhone, each Friday I profile a different reagent that is commonly encountered in Org 1/ Org 2. Calibration curves of each of the individual lanthanides and their mixtures are studied in the concentration range 0.2-25 μg/mL. Hence, the exploration of efficiently heterogeneous catalysts for coupling carbon dioxide with epoxides is really desired. Synthesis of a unique trisaccharide having an acetal linkage between open-chain and cyclic sugar found in the cell wall of Proteus. Further increasing of La addition from 6% to 8% led to decrease of the surface Ni content and the catalytic activity obviously. © 2008-2020 ResearchGate GmbH. catalyzed the formation of lariciresinol from (±)-pinoresinols and the formation of secoisolariciresinol from (±)-lariciresinols. Finally , the conditions described in this work were shown to be very competitive, especially for aliphatic nitro compounds that are usually difficult to reduce.

the trivalent lanthanide ion. Four sterols were detected by gas-liquid chromatography and.
