Description
  • The partial molar volume at infinite dilution in water (standard partial molar volume) is a property that is essential in a process to obtain the solute standard chemical potential in wide ranges of temperature and pressure. A systematic study of selected organic solutes is in progress in our laboratory. A large set of experimental data is already available and thus a development of a group contribution method for estimation of partial molar volumes is possible. Estimation methods for partial molar volumes published in the literature (e.g., recent paper by Lepori and Gianni [1]) are limited mostly to the temperature 298.15 K and atmospheric pressure. Here we present an attempt to develop a simple group contribution method for estimation of standard partial molar volumes in extended ranges of temperature.

  • Parciální molární objem při nekonečném zředění ve vodě (standardní parciální molární objem) je veličina, která je podstatná v procesech vedoucích ke standardnímu potenciálu v širokých intervalech teploty a tlaku. Systematická studie vybraných organických látek je prováděna v naší laboratoři. Je již dostupný rozsáhlý soubor experimentálních dat, což umožňuje vypracování skupinově-příspěvkové metody pro odhad parciálních molárních objemů. Odhadové metody publikované v literatuře (např. nedávná práce Leporiho a Gianniho) jsou většinou omezeny na teplotu 298,15 K a atmosférický tlak. My zde prezentujeme pokus o vývoj jednoduché skupinově-příspěvkové metody pro odhad standardního parciálního molárního objemu v rozšířených intervalech teploty. (cs)
