ABSTRACT

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
