ABSTRACT

The densities and ultrasonic velocity of the binary mixtures methyl tert-butyl ether (MTBE) or ethyl tertbutyl ether (ETBE) + (o-xylene, m-xylene and p-xylene) at the range 288.15 323.15K and atmospheric pressure, have been measured over the whole concentration range. The experimental excess volumes and deviation of isentropic compressibilities data have been analyzed. The experimental values have been studied in terms of different theoretical models. The gathered data improve open literature related to gasoline additives, as the comparison has proved, and help to understand the ether effect into aromatic environment in terms of steric hindrance and oxygen group polar potency.
