Abstract:V diplomskem delu smo predstavili aparaturo za merjenje gostot pri povišanih tlakih in temperaturah. Z gostotomerom z nihajočo U-cevko smo merili nihajne čase čistega n-heksana, n-heptana in n-oktana ter njihovih binarnih mešanic. Iz dobljeni podatkov smo izračunali njihove gostote. Gostote n-heksana, n-heptana in n-oktana ter njihovih binarnih mešanic smo izmerili pri temperaturah (303,15, 313,15, 323,15 in 333,15) K in pri tlakih (0,1, 10, 20 30 in 40) MPa. Odstopanja eksperimentalnih vrednosti gostot n-heksana, n-heptana in n-oktana smo primerjali z vrednostmi iz literature. Iz gostot n-heksana, n-heptana in n-oktana ter njihovih binarnih mešanic smo izračunali presežne molske volumne, koeficient izotermne stisljivosti in prostorninski razteznostni koeficient. Predstavili smo odvisnost termodinamskih lastnosti n-heksana, n-heptana, n-oktana ter njihovih binarnih mešanic od temperature, tlaka in sestave.
Keywords:n-heksan, n-heptan, n-oktan, presežna molska prostornina, izotermna stisljivost, prostorninski razteznostni koeficient, gostota.

Title:THERMODYNAMIC PROPERTIES OF BINARY MIXTURES OF n-HEXANE,n-HEPTANE AND n-OCTANE
Abstract:The equipment for measurement of densities at high temperatures and pressures is presented in this thesis. Densities of n-hexane, n-heptane, n-octane and their binary mixtures were measured using a vibrating tube densimeter at temperatures (303.15, 313.15, 323.15 and 333,15) K and at pressures (0.1, 10, 20, 30 and 40) MPa. Deviations of experimental values of densities of n-hexane, n-heptane and n-octane are compared with literature values. Excess molar volumes, isothermal compressibilities and isobaric thermal expansivities were calculated form obtained densities of n-hexane, n-heptane and n-octane and their binary mixtures. We have presented the dependence of thermodynamic properties of n-hexane, n-heptane, n-octane and their binary mixtures on the temperature, pressure and composition.
Keywords:n-hexane, n-heptane, n-octane, excess molar volume, isothermal compressibility, isobaric thermal expansivity, density.
