The goal of the work: design of supernucleophilic (oxidative-nucleophilic) ONS capable of governing the reaction rates and courses. Investigation techniques: UV spectrophotometry, potentiometric measurements; IR, NMF1H and NMR13C methods; general procedures of chemical synthesis were also used. Scientific merits: factors governing the micellar effects in ONS on the basis of the three modifications of the detergents were found to be of the same type. Increased hydrophobicity of substrate and alkyl substituent, decrease in the number of methylene units in the bridge group gives rise to an increase of the observed reaction rates in the micellar phase and, hence, micellar effects in the detergents. The micellar effects are 10-10000 times as compared with the observed reaction rates in water. It is these factors which are responsible for reagents concentrating in the micelles of the detergents. Practical implications: the results may be used in purposeful design of ONS in decomposition of ecotoxicants. Scientific novelty: development of the chemical reactions theory in ONS, ascertaining relationships "detergent (substrate) structure - micellar effects". Field of application: environmental protection. Subjects of investigation: organized nano-sized systems (ONS) on the basis of dimeric and functional dimeric detergents in decomposition of ecotoxicants. The goal of the work: design of high-efficiency ONS on the basis of dimeric and functional dimeric detergents in destruction of ecotoxicants. Investigation techniques: UV spectrophotometry, conductometry, tensometry; IR, NMF1H and NMR13C methods; the use of general procedures of chemical synthesis. Scientific merits: the use of ONS as a basis for "green" technologies in utilization/detoxication of ecotoxicants. Scientific novelty: new tailored amphiphilic compounds with manageable efficiency of solubilization of hydrophobic substrates, low critical concentration of micelle formation, etc. were developed. The factors, responsible for micellar effects of dimeric cationic and dimeric anionic functional detergents in destruction of ecotoxicants were established. This makes it possible to formulate information block "structure-property". Field of application: environmental protection. Product Description popup.authors Бєлоусова І.О. Бобошко Л.Г. Бураков М.І.
