“…The acetate, on the other hand, due to the existence of the C�O functional group, can be only an acceptor of the hydrogen. The previous research 1−5 showed that this kind of compound combination results in positive deviations in V E and confirmed the presence of weak hydrogen bonds between heteromolecules 2,6 in the mixture which cannot overpower the expansion of the volume due to the disruption of interactions between molecules of alcohol and negative structural effects with higher and branched alcohols. From Figure 3, it also can be concluded that not only branching, but the length of the lateral alkyl group itself has a large influence, which is noticeable by the increased V E values for the system with isobutanol compared to the system with isopentanol.…”

“…Differences for density data are below 2 kg·m –3 , for dynamic viscosity mostly less than 0.07 mPa·s, for refractive index up to 8 × 10 –3 , and for speed of sound less than 2.3 m·s –1 . While the investigated alcohols are already measured through our previous research, − , verification of experimental measurements for pure isoamyl acetate is presented by detailed graphical comparison ,,,− for all measured properties in the whole investigated temperature range in Figure .…”

“…Besides natural banana flavor it can also be used for the preparation of many synthetic flavors (apple, pear, even coffee). Research presented in this paper is a continuation of our previous investigations of binary mixtures consisting of esters and alcohols, − where our focus was on esters naturally occurring as wine components.…”

Three binary mixtures consisting of isoamyl acetate and 1-butanol or isobutanol or isopentanol were experimentally investigated in terms of their density, viscosity refractive index, and ultrasonic speed of sound, in the temperature range from 288.15 to 323.15 K and at atmospheric pressure. The choice of mixtures was based on their potential for practical application. From experimental data, excess molar volume, viscosity deviation, excess molar Gibbs free energy of activation of viscous flow, deviation in refractive index, and deviation in isentropic compressibility are calculated, correlated with the Redlich–Kister equation and used for better understanding of molecular interactions between the mixture components. Also, partial molar volumes, excess partial molar volumes, and partial molar volumes at infinite dilutions were calculated to elucidate the nonideal behavior of the investigated mixtures. Since the mixtures were investigated both from the theoretical point of view and with the aspect for practical application, the modeling of two key properties, viscosity and excess molar volume, was performed with different models and approaches, and the results are compared with experimental values.
