Abstract The phase equilibria of the Sb2Te2S-Bi2Te2S system was studied by powder X-ray diffraction (PXRD), differential thermal analysis (DTA), scanning electron microscope (SEM) and energy dispersive X- ray (EDX) microanalysis. It was shown that due to incongruent melting of the Sb2Te2S compound the system is non-quasibinary, but it is stable below the solidus and characterized […]
Abstract In the paper, the results of research into the development of polymer composition materials with improved strength and antifriction properties based on high-density polyethylene (HDPE), as well as low- density polyethylene (LDPE) and modifying additives – Azerbaijani clays and synthetic lubricating oil are presented. It was established that the introduction of 5-25% nano-sized clays […]
Abstract By polycondensation of 2-hydroxypropyl-1,3-bis-carboxymethylesterosulfoimide of saccharin-6- carboxylic acid with ethylene glycol, a thermostable polyhydroxyester was obtained. The structure of the synthesized compound was confirmed by data of the infrared spectroscopy and the thermal stability studied by a method of differential-thermal analysis on a derivatograph of “Paulik—Paulik Erdei” system. The derivatographic investigations showed that the […]
Abstract The article deals with the issue of CO2 utilization by sodium hydroxide absorption. Sodium hydroxide (NaOH) is able to react with CO2 under atmospheric conditions to form carbonate or bicarbonate ions in solution. This study focuses on the absorption of CO2 by an alkaline solvent in a bubble column. Carbonate or bicarbonate ions were […]
Abstract The interaction of benzalacetone with mercaptoacetic acid and its alkyl esters was used to synthesize and characterize new representatives of β-ketosulfides, the structure of which was proved by 1H and 13С NMR- spectroscopy. The gravimetric method was used to study the influence of the synthesized compounds on the corrosion rate of St-3 in various […]
Abstract The data on the synthesis of the new monomer benzamidmetacrylate are presented in the article. Its composition and structure were established by physical and chemical methods of research. The regularities of radical homopolymerization reactions in mass and in benzene solution were studied with the aim of creating a new biocidal polymeric material for medical […]
Abstract The IR spectrum of DIAION CRBO2 anionite synthesized on the basis of a chelating agent, a styrene macromolecule with a glucamine functional group, has been studied. Sorption properties of anionite with respect to the germanium(IV)-copper(II)-Cl-system have been studied.. It is shown that the interaction of hydroxyl and amino groups of anionite with germanate and […]
