Polar effect of successive fluorination of dimethyl carbonate on physical properties

Successive fluorination of dimethyl carbonate (DMC) exerts a polar effect on various fundamental properties. We describe the temperature dependence of the mass density (p), refractive index (n D ), relative permittivity (e r ), dynamic viscosity (η), and kinematic viscosity (v) of trifluorinated, difluorinated, and monofluorinated DMCs (TFDMC, DFDMC, and MFDMC, respectively).η decreased in essentially the same order as e r : DFDMC > TFDMC > MFDMC > DMC. However, ν and the boiling point of the TFDMC were lower than those of the MFDMC.
