“…The literature data of the binary system of ETBE + PPN was used in the regressing of H E of this binary system. Both isobaric and isothermal data together with the new H E data agreed well with the model as seen from the reported model deviations in Table .…”

“…The VLE model was capable of correlating the VLE and H E data for all of the binary systems. Furthermore, VLE data from literature for the binary system ETBE + PPN was successfully used to regress the measured H E data of the same system at lower temperature.…”

“…The vapor−liquid equilibrium (VLE) was measured using a circulation still of Yerazunis-type 11 with minor modifications to the original design. 12,13 The liquid volume needed for running the apparatus was approximately 80 cm 3 . Pressure was measured with a pressure transducer PMP 4070 (Druck) connected to Red Lion panel meter with accuracy of 0.04 kPa.…”

“…The thermodynamic properties of the binary mixtures of these ethers and nitriles are scarcely studied. Only for the binary system of ETBE + PPN isothermal VLE data have been published at 312.85 K and at 358.32 K and isobaric data at 102.6 kPa and at 65.2 kPa . For the binary systems of ETBE + ACN, TAEE + ACN, and TAEE + PPN no data are reported in open literature.…”

Vapor−liquid equilibrium (VLE), excess molar enthalpies (H E ), and excess molar volumes (V E ) provide complementary data for thermodynamic models. In this work, new data of binary mixtures of acetonitrile (ACN) or propanenitrile (PPN) with 2-ethoxy-2-methylpropane (ETBE) or 2-ethoxy-2-methylbutane (TAEE) are reported. Isothermal VLE data were measured by using a circulation still at 333 K for ETBE + ACN, at 343 K for TAEE + ACN, and at 363 K for TAEE + PPN. H E were measured by using a SETARAM C80 calorimeter equipped with a flow mixing cell at 298 K for all four binary systems. V E were measured by using an Anton Paar DMA 512P densimeter at 298 K for all four binary systems. H E data and measured VLE data, or literature VLE data for the binary system of ETBE and PPN, were used for the optimization of Wilson model parameters by using VLEFIT software. Redlich−Kister equation parameters were separately regressed for the V E data.

“…It is necessary to obtain an exact knowledge of the thermodynamic properties and transport properties of ether compounds for their applications. In recent years, much research has been focused on vapor–liquid and liquid–liquid equilibria, − thermodynamic excess properties, − density, ,− viscosity, ,, the speed of sound, and the solubility of ETBE and TAME binary and ternary mixtures with a series of substances, such as water, alcohols, ethers, hydrocarbons, ionic liquids, and other organic fluids. However, reports on the thermophysical properties of pure ETBE and TAME are have been scarce until now, which are considered to be the foundation of multicomponent systems that include ETBE or TAME.…”

Thermal Diffusivity of 2-Ethoxy-2-methylpropane (ETBE) and 2-Methoxy-2-methylbutane (TAME) at Temperatures from (293 to 523) K and Pressure up to 10 MPa

The thermal diffusivities of 2-ethoxy-2-methylpropane (ETBE) and 2-methoxy-2-methylbutane (TAME) (mass purity > 0.990, GC) were measured by the dynamic light scattering method. The investigated p–T regions are T = (293 to 523) K and p = (4 to 10) MPa, including saturated liquid, saturated vapor, and liquid. The expanded relative uncertainty in thermal diffusivity was estimated to be less than 2.4% over the whole investigated range. The influences of temperature and pressure on thermal diffusivity were presented. The empirical correlation of thermal diffusivities for both saturated liquid/vapor and liquid were also proposed with absolute average relative deviations (AARDs) of 0.22 and 0.26% for saturated-liquid ETBE and TAME, 0.13 and 0.20% for saturated-vapor ETBE and TAME, and 0.23 and 0.69% for liquid ETBE and TAME, respectively.
