Abstract

z gostotomerom smo izmerili gostote raztopin cikloheksana z ogljikovim tetrakloridom pri 288.15, 293.15 in 298.15 K ter raztopin toluena z benzenom pri 293.15, 298.15 in 308.15 K in iz njih izračunali presežne molske volumne. S pomočjo Floryjeve teorije za raztopine smo za sistem cikloheksen-oljikov tetraklorid pri 298.15 K izračunali presežno molsko entalpijo. Izračunana vrednost za ekvimolarno mešanico se relativno dobro ujema z eksperimentalno določeno.

Secondary title: Presežni molski volumni raztopin cikloheksana z ogljikovim tetrakloridom in toulena z benzenom pri različnih temperaturah
Secondary abstract: Excess molar volumes of binary mixtures of cyclohexane - carbon tetrachloride at 288.15, 293.15, 298.15 K and toluene-benzene at 293.15, 298.15, 308.15 K have been determined using a vibrating tube densimeter. Flory`s theory of liquid mixtures has been applied to calculate the excess entalphy of cyclohexane - carbon tetrachloride at 298,15 K. The calculated value for the equimolar mixture is in fairly good agreement with experimental results.
