Densities, Sound Speed, and IR Studies of (Methanol + 1-Acetoxybutane) and (Methanol + 1,1-Dimethylethyl Ester) at (298.15, 303.15, 308.15, and 313.15) K

Abstract

Densities and sound speeds for (methanol + 1-acetoxybutane) and (methanol + 1,1-dimethylethyl ester) have been measured over the entire range of compositions, at temperatures of (298.15, 303.15, 308.15, and 313.15) K and at atmospheric pressure of about 0.1 MPa. From the experimental values of density and ultrasonic velocity, the excess molar volumes V E and deviations in isentropic compressibility Δκ s have been calculated. The V E and Δκ s are negative for both the binaries studied over the whole composition. FT-IR studies of these mixtures are also carried out at T = 298.15 K.
