We describe the temperature dependence of relative permittivity (epsilon(r)), mass density (rho), refractive index (n(D)), and dynamic viscosity (eta) of monofluorinated propylene carbonate (FPC) as a highly polar liquid. The physical properties are compared with those of propylene carbonate (PC). The value Of Er of FPC is as large as 196 even at 20 degrees C. The rho and eta of FPC are also much higher than those of PC.
