Abstract

The densities and ultrasonic velocity of the binary mixtures ethanol + (benzene, toluene, ethylbenzene, isooctane, tert-butyl alcohol and xylene isomers) at the range 288.15-323.15 K and atmospheric pressure, have been measured over the whole concentration range. The experimental excess volumes and deviation of isentropic compressibilities data have been correlated with a Redlich-Kister type polynomial accurately. The gathered data improve open literature related to gasoline additives, as the comparison has proved, and help to understand the ethanol volumetric and acoustic trend into different chemical environment.
