One of the options for the disposal of worn car tires is low-temperature pyrolysis, the target product of which is pyrocondensate. The fractional composition and properties of pyrocondensate of pyrolysis of rubber waste obtained at an industrial plant are studied. The pyrocondensate was separated into gasoline and diesel fraction and residue. The composition and properties of these fractions have been studied in detail. X-ray fluorescence analysis and IR spectroscopic studies of pyrocondensate and narrow fractions isolated from it were performed.

The heterometallic Sb(III)/Li cage complex [{Sb(P-t-Bu)3}2Li6·6THF] (1) is obtained by the low-temperature (<0°C) reaction of Sb(NMe2)3 with t-BuPHLi (1:3 equiv) in THF. Thermolysis of this reaction solution leads to the formation of the bicyclic distibane [(t-BuP)3Sb]2 (2). 31P NMR spectroscopic studies reveal that this process involves initial formation of [(t-BuP)3Sb]– and [t-Bu(H)PP-t-Bu]– anions. Complexes 1 and 2 have been characterized in the solid state by X-ray diffraction studies.Key words: antimony, lithium, cage.

Thin nanocomposite films composed of ZnO and SnO2 at 0.5–5 mol.% concentrations were synthesized by a new solid-phase low-temperature pyrolysis under the developed protocols. This hetero-oxide material was thoroughly studied by X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AES) techniques to be compared with electrical and gas-sensing properties. We have found that the films have a poly-nanocrystal structure of ZnO and SnO2 crystals with characteristic grain sizes at 10–15 nm range. When comparing the chemiresistive response of the films with varied tin dioxide content, the sample of Sn:Zn optimum ratio taken as 1:99 yields 1.5-fold improvement upon to 5–50 ppm NO2 exposure at 200 °C. We argue that these remarkable changes have matured from both a reducing the intergrain potential barrier down to 0.58 eV and increasing the concentration of anionic vacancies at this rational composite. The results demonstrate that solid-phase low-temperature pyrolysis is a powerful technique for adjusting the functional gas-sensing properties of hetero-oxide film via modifying the ratio of the oxide components.

Synthetic procedures are described that allow access to anilinium salts containing the complex anions [Hg2Cl62-, [Hg2Cl4X2]2- (X = Br, I), [CdHgI6]2-, [CdHgI4Br2]2- and [CdHgBr4I2]2--. Isolated dimeric structures are proposed for the new complexes in the solid state, using X-ray powder patterns, Far-IR and Raman spectra. The spectral detail is greatly enhanced in measurements at low temperature (∼100 K).
