Temperature and pressure dependence of volumetric properties for binary mixtures of n-heptane and n-octanePečar, Darja (Avtor) Doleček, Valter (Avtor) density measurementspartial molar volumeexcess molar volumeisothermal compressibilityisobaric thermal expansivityinternal pressuren-heptanen-octaneThe densities of n-heptane, n-octane and their binary mixtures were measured at 298.15, 323.15 and 348.15 K and within the pressure range 0.1 to 40 MPa using a vibrating tube densimeter. The reliability of this technique has been verified in our previous works. The partial molar volumes, excess molar volumes, isothermal compressibilities, isobaric thermal expansivities and internal pressures were calculated from the obtained densities. This study presents the dependence of densities, partial molar volumes, excess molar volumes, isothermal compressibilities, isobaric thermal expansivities and internal pressures on composition, temperature and pressure.20072015-07-10 18:19:54Znanstveno delo52781ISSN: 1318-0207UDK: 541OceCobissID: 14086149COBISS_ID: 11695894ISSN pri članku: 1318-0207NUK URN: URN:SI:UM:DK:SYYJ4VZGsl
