The interrelation of reactivity and physical properties with values of topological indices of environmental symmetry to predict capacity of these indices in a series of 5,5-dialkoxytetrachlorocyclopentadienes has been described.
In the work thermodynamic equations of phase equilibrium of double and triple components, which form solution at limited and non – limited interval, were obtained. These equations can be used for calculation of liquidus surface and eutectic of ideal systems, as well as systems, which move away from ideal state.
Phase equilibriums in the Tl5Te3-Tl4PbTe3-Tl9BiTe6 (A) system were investigated using DTA, EMF, X-ray methods and measurement of microhardness. Three ray polythermal sections as Tl5Te3-Tl8+х+yPbуBiхTe6 type, projection of liquidus and solidus surfaces of the system (A) and graphics of dependence of microhardness, EMF and parameters of crystalllatice on concentration were constructed. It was established that the […]
α-Modification of para-aminobenzene asid has been synthesized and its molecular and crystal structure established. As distinct from β-modification and other derivatives, its molecular structure consists of monomer molecules connected by hydrogen links into single framework.
Research into compositional material has been made on the basis of clays of different deposits of Azerbayan ( Sumqayitchay, Zikh and Absheron ) as well as dolomite in Qobustan deposit. The experimental results demonstrate that to obtain high strength clay-dolomite compositions, the samples have to be baked at 750oC temperature. The maximum strength data were […]
Synthesis of bis-diasacrown ethers by means of condensation of 4-tetra-hydroftal anhydride and its dibrom-derivative with hydroxyl-substituted diasacrown compound has been performed. Structure of compounds obtained has been established through study into their IR spectrum and chemical transformations.
The possibility of the alkaline-mineral binder on the basis of the chloride soda has been considered.
Radically initiated copolymerization of N-allylmaleimide with electron-donor monomers – styrene and trans-stilbene has been carried out and investigated. It has been established by chemical, spectral and kinetic methods of analysis that copolymerization reaction proceeds on double bonds of imide cycle and allyl multiple bonds do not participate in the chain growth reaction. The formation of […]
Using the reaction of 2-hydroxi-5-alkylphenylmetylsulphides with sulphur monochloride and by subsequent reduction of reaction mixture with hydrogen 2-hydroxy-3-methilthio-5-alkylthiophenols has been syntesized. The antioxidant properties of compounds examined by chemiluminesence metods showed that they possess high antioxidant activity and by their effectiveness are supperior to the known antioxidant of ionol type.
Antimicrobial properties of 1-pyperidino-3-(2‘,4‘,6‘-trimethylphenyl)-2-propanol hs been analysed and its x-ray structure examined on modern X-ray equipment.
