Excess volumes, densities, speeds of sound and viscosities of binary systems of diisopropyl ether and acetates at 303.15 K

Abstract

Excess volumes, speeds of sound and viscosities at 303.15 K for the binary mixtures of diisopropyl ether (DIPE) + methyl acetate (MA) + ethyl acetate (EA) butyl acetate (BA) and + isoamyl acetate (IAA) were measured as a function of mole fraction over the entire range of composition. Insentropic compressibilities were computed from speed of sound and density data. Densities were obtained from experimental excess volume data. Speeds of sounds were evaluated using Jacobson free length theory and Schaaffs collision factor theory. The viscosity data were analyzed on the basis of corresponding states approach and Grunberg and Nissan treatment. The experimental results on excess volume, deviations in isentropic compressibility and in viscosity were discussed in terms of molecular interactions between unlike molecules.
