STUDY OF THERMODYNAMIC PROPERTIES OF BINARY SOLUTIONS (1, 2-PROPANEDIOL + BUTYL ACETATE)

Densities and excess molar volumes of the binary system of (1, 2-propanediol + butyl acetate) have been measured as a function of concentration at temperatures 283, 293, 303, 313 K and atmospheric pressure by density meter (anton paar DMA-4500). The density of the mixture, at constant temperature with increasing concentration, increased and decreased with increasing temperature at constant concentration. Excess molar volumes were fitted to redlich- kister expression which 5 degree of polynomial expansion. The standard deviations between experimental and computational data for this system at different temperatures are close to zero.
