Volumetric and acoustic studies of binary liquid mixtures of alkoxypropanols with ethyl acetoacetate in the temperature range (288.15-308.15) K

摘要

Densities and speeds of sound for the binary liquid mixtures of propylene glycol monomethyl ether, propylene glycol monoethyl ether, propylene glycol monopropyl ether, and propylene glycol monobutyl ether with ethyl acetoacetate, have been measured over the entire composition range at temperatures T = (288.15, 293.15, 298.15, 303.15, and 308.15) K and atmospheric pressure. The density values have been used to calculate excess molar volumes (V_m~E ), while speeds of sound data have been used to calculate deviation in isentropic compressibility (Δ Ak_s ). The changes in these properties with the composition and temperature have been discussed in terms of molecular interactions existing in the solution phase.
