Karazin popup.description2 The purpose of work - establishment of solubility and solvatation laws of alkaline metals salts in polyethylene glycols, research of the general and specific laws of alkaline metals salts with polyethylene glycol, establishment the relative contribution of various types of interpartial interactions to processes of dissolution and solvation salts with ions different of nuture Method of research - performance of work is carried out with use of modern radioanalytical and spectroscopic methods.For the first time researches of solubility KNCS, NaH2PO4, КH2PO4, Na2SO4 in polyethyleneglycolses of various molecular weights are lead by methods: photometric,a radionuclide X-ray and atomic-emission spectrometry. by a method of radioactive indicators, a radionuclide X-ray fluorescent method of the analysis and atomic-emission spectrometry IR?spectroscopic researches of interaction of salts of alkaline metals of metals with polyethylene glycols are carried out. Influence of number oxyethylic groups (-СН2ОСН2-) on solvation and complecsation properties polyethylene glycols is investigated; the relative contribution of various types of interpartial interactions to processes of dissolution and solvation is established, the general laws and specific features of interaction cation alkaline metals with oxiethylic glycols are investigated. The mechanism specific solvatation cation alkaline metals polyethylene glycols and influence on it conformations conditions of molecules of polyethylene glycols is established.It is shown, that not additive behavior of solubility КH2PO4 і К2SO4 in the mixed systems is caused a lot of factors: character of interpartial interactions in the mixed solvent and interaction of an ion specific a donor-aseptic ion with polyethylene glycolses Product Description popup.authors popup.nrat_date 2020-04-02 Close
