ABSTRACT

In this contribution, we report different thermophysical properties for two derivatives of heterocyclic compounds (2-ethylthiophene and 2-ethylfuran): density, speed of sound, surface tension, kinematic viscosity, and static permittivity at atmospheric pressure (p = 0.1 MPa) from T = 278.15 K to 338.15 K. Furthermore, refractive index has been analysed in the temperature range from T = 283.15 K to 338.15 K. Additionally, density values have been obtained at pressures up to 65 MPa in the temperature range (283.15 - 338.15) K. Moreover, vapor pressures have been determined. Different derivate properties, such as isobaric expansibility, isentropic and isothermal compressibility, molar refraction, dynamic viscosity, enthalpy and entropy of surface formation per unit surface area, and enthalpy of vaporization have been calculated from experimental results. Finally, these properties have been analysed and compared with previous data published in the literature for the same and related compounds.
