Viscosity and Density of Water + Ethyl Acetate + Ethanol Mixtures at 298.15 and 318.15 K and Atmospheric Pressure

Abstract

The viscosities and densities of the ternary mixtures water + ethyl acetate + ethanol and their constituent binaries have been measured at 298.15 and 318.15 K and atmospheric pressure. The excess molar volumes, V m E , and viscosity deviations, ∆η, were calculated from density and viscosity, respectively. A rational function due to Myers and Scott was used to describe the composition dependence of these properties. To describe the ternary system, binary pair additivity and the Pando et al. rational functions for the ternary contributions (∆η T and V T E) were considered.

Viscosimetric behaviour of hyaluronic acid in different aqueous solutions

“…In relation to the apparent viscosity magnitude, an increase in this value is observed when the ethanol concentration increases in the mixture. This behaviour is due to the addition of ethanol to pure water, which also produces an increase in viscosity (Pires, Costa, Ferreira, & Fonseca, 2007) until a maximum. For this reason, the increase in viscosity shown in Fig.…”

Study of Internal Pressure and Related Parameters in Ternary Liquid Mixtures Using Ultrasonic Velocity Measurement

“…In other words, structural contributions arising from geometrical fitting of one component into the other because of differences in the free volume and molar volume between components lead to a overall negative contribution to V m E . Here in the present mixtures, it may be concluded that the chemical or specific intermolecular interactions dominate over the other types of interactions [23,24].…”

Spray characteristics of a swirl atomiser in trigger sprayers using water–ethanol mixtures

“…The fluid surface tension, viscosity and density values are listed in Table 1 for different mixtures. These properties are obtained from published physical properties for water–ethanol mixtures 24, 25. Since the changes on fluids viscosities and density are relatively small, the effects of viscosity and density on the spray characteristics and atomisation are expected to be minor.…”
