A series of polymethine thiopyrylium dyestuffs of symmetrical and unsymmetrical structure, containing one to fourtert-butyl groups, has been synthesized from 6-tert-butyl-2-(p-tert-butylphenyl)-4-methyl-, 4,6-di(tert-butyl)-2-methyl-, and 6-tert-butyl-2,4-dimethyl-1-benzothiopyrylium perchlorates. 相似文献

Catalytic pyrolysis of ethylene was carried out at 700 °C in the presence of vapors of H2O, EtOH, NH4OH, PCl3, (MeO)3P, Me2SO4, (MeO)3B, and HCl. The composition of solid pyrolysis products was studied using the elemental analysis, X-ray diffraction analysis,
and electron microscopy. The composition of the gaseous pyrolysis products was studied using mass spectrometry. The processes
in the gas phase were characterized, and the relationship between conditions of ethylene pyrolysis and the structure of formed
carbon nanofibers was revealed. The introduction of gaseous additives has a substantial effect on the formation, growth, and
structure of the carbon nanofibers formed. 相似文献

Conclusions The reaction of pentafluoro-N-(2,3,4,5,6-pentafluorobenzylidene) aniline with peracetlc acid or 90% hydrogen peroxide in CH2Cl2 at 20°C yields -pentafluoroanilino-2,3,4,5,6-pentafluorobenzylhydroperoxide. Its capability for thermal and photolytic transformation into bis (-pentafluoroanilino-2,3,4,5,6-pentafluorobenzyl) peroxide was shown.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 3, pp. 665–668, March, 1985. 相似文献

2-(2-(Dimethylamino)vinyll-6 pentafluorophenyl-4-phenylpyryliunt perchlorate has been synthesized and it was shown that it is readily converted into 2-fornrylntethylene-6-pentafluorophenyl-4-phenyl-2H-pyran on chromatography on alkaline Al2O3. The stereoisornerism of the synthesized compounds has been studied by PMR spectroscopy.Novosibirsk Institute of Organic Chemistry, Siberian Branch of the Russian Academy of Sciences (SO RAN) Novosibirsk 630090.

Sorption of nonferrous metal ions under static conditions by a composite sorbent based on titanium phosphate was studied. The distribution coefficients and exchange constants for Cu(II), Ni(II), and Co(II) were calculated from the experimental data. The kinetics of the sorption of multiply charged ions from dilute hydrochloric acid solutions was studied, and the diffusion coefficients of exchanging ions were determined. 相似文献
