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

Densities and speeds of sound for the binary liquid mixtures of propylene glycol monomethyl ether (1-methoxy-2-propanol), CH 3 OCH 2 CH 2 CH 2 OH, propylene glycol monoethyl ether (1-ethoxy-2-propanol), C 2 H 5 OCH 2 CH 2 CH 2 OH, propylene glycol monopropyl ether (1-propoxy-2-propanol), C 3 H 7 OCH 2 CH 2 CH 2 OH, and propylene glycol monobutyl ether (1-butoxy-2-propanol), C 4 H 9 OCH 2 CH 2 CH 2 OH, 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, Δκ S . The results have been discussed in terms of intermolecular interactions and their dependence on the composition and temperature.
