Conclusions The oxidative dehydrogenation of C5 paraffin hydrocarbons on Fe catalysts in the presence of HCl leads mainly to the formation of unsaturated hydrocarbons, which have the same structure of the carbon skeleton as the starting hydrocarbon, in which connection the yield of olefinic hydrocarbons proved to be substantially higher (25% from isopentane and 32% from n-pentane) than the yield of dienes (respectively 15% of isoprene and 11% of piperylene).Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 11, pp. 2599–2601, November, 1972. 相似文献

The specific features of elastic scattering of volume waves and surface plasmon polaritons by polycrystalline gold films have
been investigated. An analysis of the relative scattered energy, power spectral density of surface roughness, and integral
and angular dependences of scattering of waves of different nature indicates a strong nonradiative multiple scattering of
surface plasmon polaritons in gold films. When roughness increases, this scattering leads to an increase in scattering isotropy
and to a partial loss of structural information about gold films. The analysis of the scattered energy of surface plasmon
polaritons with application of the data on multifractal dimension of gold surface indicates also that the radiative scattering
of surface plasmon polaritons depends on both the rms surface roughness and the surface wave propagation length. 相似文献
