Volumetric Behaviour of Binary and Ternary Liquid Systems Composed of Toluene, Isooctane and Methyl tert-Butyl Ether at Temperatures from 298.15 K to 328.15 K
Linek, Jan ; Morávková, Lenka ; Wagner, Zdeněk
The densities and speeds of sound of the binary systems toluene plus isooctane, MTBE plus toluene and MTBE plus isooctane and of the ternary system toluene plus isooctane plus MTBE were measured at four temperatures within 298.15 K and 328.15 K, and the respective values of excess volumes EVm and adiabatic compressibility κS were calculated. The EVm and κS values of the binary systems were fitted to the Redlich-Kister equation on applying the weighted gnostic method. The EVm values for the MTBE plus toluene system are negative and decreasing with increasing temperature. The other binary systems show positive EVm with comparatively small temperature dependence. The volumetric data on the binaries and the ternary are of practical importance and besides, serve for testing the correlation procedures for fitting and predicting ternary data from binary ones.

Dodatkové molární objemy soustav benzen + isopropylbenzen nebo + 1,2,4-trimethylbenzen nebo + 1,3,5-trimethylbenzen při teplotách mezi 298.15 a 328.15 K
Linek, Jan ; Morávková, Lenka
Hustoty kapalných soustav benzen + isopropylbenzen, benzen + 1,2,4-trimethylbenzen a benzen + 1,3,5-trimethylbenzen byly změřeny při teplotách (298.15, 308.15, 318.15 a 328.15) K pomocí vibračního densimetru. Dodatkové molární objemy vypočtené z hustotních dat poskytují teplotní závislost v rozmezí 298ů328 K.
