dc.description.abstractU ovoj doktorskoj disertaciji eksperimentalno su određene rastvorljivosti binarnih i pseudo - binarnih smeša, odnosno termodinamičke ravnoteže tečno - tečno i čvrsto - tečno, kao i uticaj dodavanja različitih ko - rastvarača na pomeranje fazne ravnoteže, na atmosferskom pritisku i u temperaturnom intervalu od 288.15 K do 371.15 K . Svi dobijeni rezultati prikazani su grafički, formiranjem faznih dijagrama temperatura - sastav. Izvršena su merenja ravnotežnih, volumetrijskih i transportnih svojstava višekomponentnih sistema ekoloških rastvarača: jonskih tečnosti, polimera i alkohola sa organskim rastvaračima. Eksperimentalno su određivana termodinamička svojstva čistih komponenata i njihovih smeša u temperaturnom opsegu od T=(288.15-333.15) K i na atmosferskom pritisku. Eksperimentalno su merene gustine, indeksi refrakcije i viskoznosti ekoloških rastvarača u smeši sa industrijskim zagađivačima. Iz eksperimentalnih podataka izračunate su dopunske molarne zapremine E V , promena viskoznosti Δη, promena indeksa refrakcije nD kao i dopunske termodinamičke veličine: E G  dopunska Gibsova energija aktivacije viskoznog toka, E S  dopunska enrtopija i E H  dopunska entalpija, koeficijent izobarske ekspanzije α, dopunski koeficijent izobarske ekspanzije αE. Izračunate termodinamičke veličine su korišćene za analizu specifičnih molekulskih interakcija i efekata mešanja između komponenata smeša, uzimajući u obzir geometrijska pakovanja između komponenata i uticaj temperature. Ravnotežni podaci čvrsto - tečno za sva četiri binarna sistema su uspešno korelisani NRTL modelom sa dva različita temperaturno zavisna parametra, 12 g i 21 g Fourier-ova transformaciona infracrvena (FT-IR) spektroskopija binarnih smeša nikotina sa alkoholima i odgovarajućih čistih komponenata izvedena je na 298.15 K. u cilju pojašnjenja molekulske strukture, intra - i inter - molekulskih interakcija u rastvorima. Modelovanje viskoziteta rađeno je sa dva modela: modelima doprinosa grupa UNIFAC-VISCO i ASOG-VISCO modelima, i korelativnim McAllister dvoparametarski three-body i troparametarski four-body modelima...sr
dc.description.abstractIn this doctoral dissertation, binary and pesudobinary mixtures were experimentally determined. Those were thermodynamic equilibrium liquid - liquid and solid - liquid, as well as the influence of adding different co - solvents on the phase balance displacement at atmospheric pressure and in the temperature range from 288.15 K to 371.15 K. All obtained results are presented graphically by forming phase diagrams of temperature - content. Measurements of equilibrium, volumetric and transport properties of multicomponent ecological solvent systems were performed: ionic liquids, polymers and alcohols with organic solvents. The thermodynamic properties of pure components and their mixtures in the temperature range from T = (288.15-333.15) K and at atmospheric pressure were determined experimentally. Density, refractive indices and viscosity of organic solvents in mixtures with industrial pollutants were experimentally measured. Complementary molar volumes E V , change in viscosity Δη, change in refractive index nD , as well as additional thermodynamic sizes were computed from the experimental data: E G  additional Gibbs viscosity current activation energy, E S  supplemental entropy and E H  supplemental enthalpy, coefficient of isobar expansion α, supplementary iso-expansion expansion ekspanzije αE. The calculated thermodynamic quantities were used to analyze specific molecular interactions and mixing effects between the components of the mixture, taking into account the geometric packings between the components and the effect of the temperature. The equilibrium data firmly-fluently for all four binary systems were successfully correlated with the NRTL model with two different temperature-dependent parameters 12 g and 21 g Fourier's transformation infrared (FT-IR) spectroscopy of binary mixtures of nicotine with alcohols and corresponding pure components was performed at 298.15 K in order to clarify molecular structure and intra - and intermolecular interactions in solutions...en
