چکیده انگلیسی


• Densities (ρ) and sound velocities (u) for {furfural (x1) + alcohol (x2)} systems were measured.
• Derived properties were calculated from measured ρ and u, respectively.
• Sound velocity mixing rules were applied to the experimental sound velocity.
• Redlich–Kister polynomial was used to fit the experimental results.
• The semi-empirical calculation using HyperChem 7 shows that furfural interacts with the alcohol through the H-bonding.

In this work, the study of the interactions between furfural and alcohol mixtures are discussed through insight from density and sound velocity measurements. The density (ρ) and sound velocity (u) of furfural, alcohols such as ethanol, 1-butanol, 2-butanol, and their binary systems {furfural (x1) + ethanol or 1-butanol or 2-butanol (x2)} were measured at (283.15, 293.15, 303.15, and 313.15) K and at p = 1 × 105 Pa. The sound velocity data were tested by using sound velocity mixing rules to calculate the sound velocity of the binary mixture from pure component data. The derived properties such as excess molar volumes, VmE, isentropic compressibility, κs, and deviation in isentropic compressibility, Δκs, were also calculated. The Redlich–Kister polynomial equation was used to fit the excess/deviation properties. The semi-empirical calculation with the help of HyperChem 7 shows that furfural interacts with the alcohol through the H-bonding.
