Thermophysical study of the furan family
The dynamic viscosity, speed of sound, surface tension, density, refractive index, and static permittivity of furan, 2-methylfuran and 2,5-dimethylfuran have been obtained at temperatures from 278.15 to 338.15 K under atmospheric pressure, although for furan the temperature range have been 278.15-303.15 K. The vapour pressure has been determined over a temperature range from 283.16 K to 366.70 K. Besides, the p rho T behavior has been also measured using a high-pressure, high-temperature vibrating tube densimeter over a pressure range from 0.1 MPa to 60.0 MPa and a temperature range from 283.15 K to 338.15 K. However, in the case of furan, the densities have been measured at the pressure of 0.1 MPa only in the temperature range 283.15-303.15 K. Furthermore, some derived properties such as isobaric expansibilities, isothermal compressibilities, molar refraction, isentropic compressibilities or dipolar moment have been calculated using the experimental data. At the end, a comparative study has been carried out taking into account the molecular structure of the chemicals investigated. (C) 2015 Elsevier B.V. All rights reserved.
