ABSTRACT
In the present work, the effect of pressure and temperature on the density, isobaric thermal expansivity, p, isothermal compressibility, T, and internal pressure, of monoethylene glycol methyl ether (MEGME), monoethylene glycol ethyl ether (MEGEE), and monoethylene glycol isopropyl ether (iso-MEGPE) has been determined. New density data (273 experimental points) have been obtained with a vibrating tube densimeter at temperatures between (293.15 and 353.15) K and pressures up to 60 MPa. The trend of the volumetric properties with the number of methylene groups in the monoethylene glycol alkyl ether molecules has been analyzed. The ability of different equations of state to predict the volumetric properties of these molecules has been tested.
