The visible light significantly increases the catalytic activity of fullerenes. The irradiation of reaction mixture in the presence of С60/С70 leads to preferred formation of esters.
Process of desiccation of monoatomic alcohols of normal (C1-C5) and isomeric (C3-C5) structures by zeolites has been examined. Desiccation degrees estimated by calculacion of the following indices: a dynamic and equilibrium adsorption activities of an adsorbent layer towards water; a length of mass-exchange zone; a degree of utilization of the adsorbent layer and its working […]
The article discussed the results of study into peculiarities of radical homo- and copolymerization of allylic compounds, «degradation» chain transfer, typical for peculiar to polymerization of these compounds as well as the role of complexing agents polymerization of allylic monomers. Review of author¢s published works and other researcher in the field of radical copolymerization allylic […]
Process of sedimentation of hard particles of hydrophobized petropolluted earth in the water dispersive environment is connected to various forms of coagulation structurization of sedimentation deposit. The work present results of strained sedimentation of particles in the hard phase under the influence of gravity during setting of water suspension of petropolluted ground. Coagulation of the […]
Ethylene oligomerization reaction in the presence of complex catalytic systems consisting of sterically hindered bi- and bis-phenol compounds of zirconium, containing various cycloalkyl and tert-butyl substituents in aromatic ring, and alkylaluminium chloride, has been investigated. Their high efficiency in ethylene oligomerization reaction identified. It has been found that in the presence of catalytic system consisting […]
Physical-chemical properties of Carthamus lanatus oil indices have first been determined. Identified in the composition of oil was hydrocarbons 0.60%, triacilglicerols 82.88%, free of acids 9.53%, sterols 2.65% and chlorophyll 1.46%. Oils are linoleic containing (content of linoleic acid is 76.5%).
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.
