Volumetric Properties of Ternary Liquid System Composed of Methyl tert-Butyl Ether, Toluene, and Isooctane at Temperatures from 298.15 K to 328.15 K. Experimental Data and Their Correlation
Morávková, Lenka ; Wagner, Zdeněk ; Sedláková, Zuzana ; Linek, Jan
The densities and speeds of sound of the methyl tert-butyl ether (MTBE) + toluene + isooctane system were measured at four temperatures over the range 298.15 K to 328.15 K, and the respective values of excess volumes EVm and adiabatic compressibility κS were calculated. The EVm and κS values for the ternary and corresponding binaries were fitted to the modified Redlich–Kister equation considering various number of ternary constants. The necessary number of ternary constants needed to describe the system within experimental error is discussed.
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.
