Název v původním jazyce

Partial molar volumes of organic solutes in water. XXIV. Selected alkane-?,?-diols at temperatures T = 298 K to 573 K and pressures up to 30 MPa.

Popis výsledku v původním jazyce

Density data for dilute aqueous solutions of three alkane-?,?-diols (pentane-1,5-diol, octane-1,8-diol, nonane-1,9-diol) are presented together with standard molar volumes (partial molar volumes at infinite dilution) calculated from the experimental data. The measurements were performed at temperatures from T = 298 K up to T = 573 K. Experimental pressures were slightly above the saturation vapour pressure of water, and (15 and 30) MPa. The data were obtained using a high-temperature high-pressure flowvibrating-tube densimeter. Measured standard molar volumes were combined with data previously published for other members of the homologous series and discussed. Experimental standard molar volumes were correlated as a function of temperature and pressure using an empirical polynomial function. Contributions of the methylene group to the standard molar volume were also evaluated and discussed. Dependences of standard molar volumes on temperature and pressure were analyzed.
