Description
  • Limitní aktivitní koeficienty 1-propanolu and 1-butanolu v heptanu a oktanu byly stanoveny za použití rovnovážné diferenciální statické aparatury vždy při 5 teplotách mezi 303 K a 343 K. Jako experimentální technika byla zvolena komparativní tenzimetrie, která je velmi vhodná pro sledované systémy a podmínky. Nová měření doplňují a rozšiřují již dříve publikovaná data o limitních aktivitních koeficientech některých nižších 1-alkanolů v n-alkánech, které jsme stanovili prostřednictvím experimentální metody inert gas stripping. Sady dat získané dvěma různými experimentálními technikami vykazují dobrou vzájemnou konzistenci. Zde prezentovaná data o limitních aktivitních koeficientech spolu s dalšími literárními informacemi a jejich teplotními trendy jsou adekvátně konzistentní s kalorimetricky získanými limitními parcialními molárními dodatkovými entalpiemi.

  • Limiting activity coefficients of 1-propanol and 1-butanol in heptane and octane were determined at 10 K increments between 303 K and 343 K using a differential static cell equilibrium apparatus. The comparative tensimetric technique was employed because it is well suited for the systems and conditions examined. The new measurements supplement and extend previously released limiting activity coeficient data for some lower 1-alkanol in n-alkanes we determined by the inert gas stripping. The sets of data obtained by the two different experimental techniques show good mutual consistency. The present limiting activity coeficient data compare favorably also with other literature information and their temperature trends are reasonably consistent with calorimetric data on limiting partial molar excess enthalpies.
