Liquid Dielectric Constants of Fluorinated Ethers, Fluorinated Ketone and Fluorinated Alcohol

Abstract

The liquid dielectric constants of twelve fluorinated ethers, four fluorinated ketones and two fluorinated alcohols which are expected as promising candidates of CFC and HCFC alternatives were measured at temperatures from 278 K to 332 K and at atmospheric pressure. The liquid dielectric constants has been measured by an LCR-meter (Hewlett Packard, HP -4285A) within an error of 0.3 %. The relation between dielectric constant and temperature has been examined over the whole range of temperature.
