20.500.12556/DKUM-53283 Excess molar volumes of binary liquid mixtures of cyclohexane-carbon tetrachloride and toluene-benzene at various temperatures Presežni molski volumni raztopin cikloheksana z ogljikovim tetrakloridom in toulena z benzenom pri različnih temperaturah 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. 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-ogljikov tetraklorid pri 298.15 K izračunali presežno molsko entalpijo. Izračunana vrednost za ekvimolarno mešanico se relativno dobro ujema z eksperimentalno določeno. physical chemistry molar volumes measurements excess enthalpy fizikalna kemija molska gostota meritve presežna molska entalpija true false true Angleški jezik Slovenski jezik Znanstveno delo 2015-07-10 19:55:30 2015-07-10 19:55:30 2022-06-02 03:09:54 2021-05-10 03:36:39 1998 0 0 str. 153-160 št. 2 Letn. 45 1998 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1318-0207 541.25 14086149 3763734 1318-0207 URN:SI:UM:DK:S3BRCPC9 Acta_Chimica_Slovenica_1998_Petek,_Dolecek_Excess_molar_volumes_of_binary_liquid_mixtures_of_cyclohexane_-_carbon_tetrachloride_and_tolu.pdf Acta_Chimica_Slovenica_1998_Petek,_Dolecek_Excess_molar_volumes_of_binary_liquid_mixtures_of_cyclohexane_-_carbon_tetrachloride_and_tolu.pdf 1 E4B7AC3B50C89783CB34EE3EF19D171D dc0b65414a349e9788aab472974d004df3811760878533e1414009000641e3b5 87842c58-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=115518 http://acta-arhiv.chem-soc.si/45/45-2-153.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=77843 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
