Description
  • Limiting activity coefficients ( ) of lower (C1-C5) 1-alkanols in water were measured at several temperatures covering the range from the freezing to the normal boiling point of water. Five experimental techniques, namely headspace analysis, inert gas stripping, comparative tensimetry, Rayleigh distillation, and the method of circulation still, were employed for the purpose. To establish reliable temperature dependence of for each of the systems, careful goal-directed measurements were carried out applying the methods alternatively in accordance with the applicability conditions. The method-to-method accord of the results, their thermodynamic consistency with calorimetric data on related thermal properties and their accuracy were verified using two procedures.

  • Limitní aktivitní koeficienty ( ) nižších (C1-C5) 1-alkanolů ve vodě byly měřeny při několika teplotách pokrývajících interval od bodu tuhnutí do normálního bodu varu vody. K tomuto účelu bylo použito pět experimentálních technik - headspace analysis, inert gas stripping, comparativní tensimetrie, Rayleighova destilace a metoda rovnovážného cirkulačního přístroje. Pro stanovení spolehlivé teplotní závislosti byla u každého systému prováděna pečlivá měření, při nichž byly aplikovány experimentální metody s ohledem na jejich aplikovatelnost. Vzájemný soulad exp. výsledků získaných různými exp. metodami, jejich termodynamická konzistence s kalorimetrickými údaji souvisejících thermalních vlastností a jejich přesnost byly ověřeny užitím dvou postupů.
