Densities and Speeds of Sound of Binary Liquid Mixtures of Some n-Alkoxypropanols with Methyl Acetate, Ethyl Acetate, and n-Butyl Acetate at T= (288.15, 293.15, 298.15, 303.15, and 308.15) K

摘要

Densities and speeds of sound for the binary liquid mixtures of propylene glycol monomethyl ether (1-methoxy-2-propanol), CH3OCH2CH2CH2OH, propylene glycol monoethyl ether (1-ethoxy-2-propanol), C2H5OCH2CH2CH2OH, propylene glycol monopropyl ether (1-propoxy-2-propanol), C3H7OCH2CH2CH2OH, and propylene glycol monobutyl ether (1-butoxy-2-propanol), C4H9OCH2CH2CH2OH, with n-alkyl acetate over the whole composition range have been measured using an Anton Paar DSA 5000 M densimeter at T = (288.15, 293.15, 298.15, 303.15, and 308.15) K and atmospheric pressure. Experimental data on density and speeds of sound have been used to derive excess quantities like excess molar volume, V_m~E, and deviation in isentropic compressibility, Δ_κ_S. The results have been discussed in terms of intermolecular interactions and their dependence on the composition and temperature.
