Relative Permittivity of Dimethylsulfoxide and N,N-Dimethylformamide at Temperatures from (278 to 328) K and Pressures from (0.1 to 5) MPa
Relative permittivities (?r) have been measured at two frequencies with an expanded (k = 2) uncertainty of 0.1 using a re-entrant radio frequency resonator in the pressure range (0.1 to 5) MPa at temperatures from (278 to 328) K for N,N-dimethylformamide (DMF) and (293 to 328) K for dimethylsulfoxide (DMSO). At 298.15 K and 0.1 MPa, the assessed literature averages of 38.4 +- 1.8 and 47.3 +- 1.8 for DMF and DMSO, respectively, are consistent with the values of 37.2 +- 0.1 and 46.0 +- 0.1 determined in this work. Possible sources of uncertainty are discussed. An empirical description of ?r(p,T) is given that can be used to calculate the temperature and pressure derivatives of ?r. Kirkwood g factors calculated using the present data show only minimal dipole-dipole correlations for both DMF and DMSO.
