The catalytic properties of cluster magnesium derivatives were studied using the self-hydrogenation reaction of unsaturated compounds as an example. In the presence of a cluster magnesium–anthracene adduct at 150–298 K, the self-hydrogenation of anthracene occurred with yields of up to 40 molecules per atom of magnesium. 相似文献

On the basis of numerical calculations and experimental studies we analyze the possibilities of measuring the electrophysical parameters of indium phosphide by means of infrared reflection spectra at wavelengths ranging from 5 to 200 m. We demonstrate that contactless nondestructive measurements of the electron density in the range 1016–1020 cm–3 can be made with a relative error not exceeding 15%, and of mobility with a relative error not exceeding 25%. A nomogram method is presented for rapid conversion of data from infrared reflection spectra into the parameters being measured.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 1, pp. 22–27, January, 1988. 相似文献

Basic kinetic parameters of the catalytic oxidation of dodecyl mercaptan in kerosene in the presence of silica-immobilized pyridinium or imidazolium chlorocuprate complexes have been determined. The composition of the copper-containing anions and the oxidation kinetics depend on the nature of the ionic liquid and on the method of its synthesis. The compositions developed in this study are usable in the removal of hydrogen sulfide and light mercaptans from the oil stripping gas. 相似文献

Spectrophotometry studies have shown that N-vinylpyrrolidone and/or maleic anhydride interact with 2,2-diphenyl-1-picrylhydrazyl radical in a solution. Thermochemical parameters of the most probable reactions involving these compounds have been estimated by means of the PM6 and B3LYP/6-31+G(d) (gas phase) density functional theory methods. It has been suggested that the stable radical is attached to the monomer molecule, the resulting radical being involved in the chain growth reactions. Termination via the oligomeric radicals recombination is the most probable. 相似文献

The application of a high‐temperature electrochemical reactor based on stabilized zirconium dioxide (0.9 ZrO20.1 Y2O3) for organic gas sampling in continuous‐flow isotope‐ratio mass spectrometry (CF‐IRMS) has been found to be efficient. This solid electrolyte reactor (SER) can also be used as a chromatographic detector for the quantitative measurements of organic gases. A three‐electrode SER system was studied. Complete stoichiometric oxidation of organic gases has been achieved at 900–950°C due to the large catalytic surface area of the porous platinum coating. At this temperature, the oxygen ions formed from the oxygen of ambient air on the outer surface of the reactor migrate through the solid electrolyte under the action of the applied electric field and allow combustion of gases being analyzed to be effected. It should be noted that oxygen gas was not introduced into the gas‐carrier flow. Similar results for the measurements of carbon isotope ratios were obtained at the oxidation of hydrocarbon gases in both the standard and the solid electrolyte reactors.

Experimental results on the products and the kinetics of the hydrogen bromide addition to alkenes-1 in non-polar solvents and on complex formation in hydrogen bromide-olefin-solvent systems are reviewed. Theoretical calculations concerning hydrogen bromide-olefin complexes are used along with the experimental evidence to suggest a molecular mechanism of addition involving intermediate cyclic structures. 相似文献
