The dielectric constant of liquid HFC32.


Dielectric constant measurements have been performed in the liquid phase for R32 (difluoromethane) in the temperature range between 208 and 304 K and pressures from the saruration up to 18 megapascals. The measurements were carried out with a direct method using an impedance analyzer. The estimated uncertainty for the data obtained is 0.01% and the accuracy is 0.1%. The data were correlated as a function of pressure.
