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%. http://pubs.acs.org/page/copyright/permissions.html, https://doi.org/10.1021/acs.jmedchem.0c00746, https://doi.org/10.1021/acs.jmedchem.9b01391, https://doi.org/10.1021/acs.jmedchem.9b01379, https://doi.org/10.1021/acs.orglett.8b02874, https://doi.org/10.1021/acs.orglett.8b02221, https://doi.org/10.1021/acs.inorgchem.6b00001, https://doi.org/10.1021/acs.orglett.5b03116, https://doi.org/10.1021/acsmedchemlett.5b00175, https://doi.org/10.1007/s00775-020-01796-x, https://doi.org/10.1016/j.tet.2020.131150, https://doi.org/10.2174/1385272823666190913185618, https://doi.org/10.1016/j.tetlet.2019.151153, https://doi.org/10.1016/j.inoche.2019.05.040, https://doi.org/10.1016/j.tetlet.2019.03.052, https://doi.org/10.1016/j.tetlet.2019.02.027, https://doi.org/10.1016/j.jechem.2018.01.021, https://doi.org/10.1016/j.tet.2018.09.011, https://doi.org/10.3390/molecules23050996, https://doi.org/10.1007/978-981-10-8806-3_2, https://doi.org/10.1016/j.chembiol.2017.08.014, https://doi.org/10.1007/s11164-017-2927-2, https://doi.org/10.1002/9781118662083.cot09-001, https://doi.org/10.1016/j.bioorg.2017.03.006, https://doi.org/10.1016/j.bmc.2017.03.047, https://doi.org/10.1002/9780471264194.fos11431.pub4, https://doi.org/10.1002/9780471264194.fos02343.pub7, https://doi.org/10.1016/j.bmc.2016.09.038, https://doi.org/10.1016/j.bmcl.2016.10.034, https://doi.org/10.1016/j.tet.2016.07.056, https://doi.org/10.1016/j.dib.2016.06.023, https://doi.org/10.1016/j.bmc.2016.04.044, https://doi.org/10.1016/j.bmcl.2016.04.027, https://doi.org/10.1016/j.carres.2016.02.010, https://doi.org/10.1016/j.ijhydene.2015.10.013, https://doi.org/10.1016/j.tet.2015.09.012, https://doi.org/10.1016/j.tet.2015.05.049, https://doi.org/10.1007/s10562-015-1531-6, https://doi.org/10.1016/j.ejmech.2015.04.036, https://doi.org/10.1016/j.tetlet.2015.03.127, https://doi.org/10.1016/j.tetlet.2015.02.131, https://doi.org/10.1016/j.tetlet.2014.08.008, https://doi.org/10.1080/07328303.2014.907907, https://doi.org/10.1080/00397911.2013.853798, https://doi.org/10.1016/j.apsusc.2013.12.036, https://doi.org/10.1016/j.tet.2013.11.040, https://doi.org/10.1016/j.ejmech.2013.09.012, https://doi.org/10.1016/j.tetlet.2013.06.072, https://doi.org/10.1016/j.bmc.2013.03.079, https://doi.org/10.1016/j.tetlet.2013.03.100, https://doi.org/10.1016/j.carres.2012.09.005, https://doi.org/10.1016/j.jorganchem.2012.05.042, https://doi.org/10.1016/j.tet.2011.10.055, https://doi.org/10.1016/j.tetlet.2011.10.155, https://doi.org/10.1002/9780471264194.fos07737.pub3, https://doi.org/10.1080/00397911.2010.488307, https://doi.org/10.1016/j.jorganchem.2011.01.027, https://doi.org/10.1002/9783527631827.ch1, https://doi.org/10.1016/j.bmcl.2010.08.091, https://doi.org/10.1002/9780471264194.fos11452.pub2, https://doi.org/10.1016/j.tetlet.2009.12.061, https://doi.org/10.1016/j.molcatb.2009.07.012, https://doi.org/10.1016/j.bmcl.2009.05.017, https://doi.org/10.1016/j.tetlet.2009.05.003, https://doi.org/10.1080/00397910802521246, https://doi.org/10.1016/j.tetasy.2008.12.006, https://doi.org/10.1016/j.jorganchem.2008.02.004. )—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.

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.
