For many years mineral oil has been used as a dielectric liquid in condensers, or capacitors, and as an insulator and heat transfer medium in transformers. During recent years the use of chlorinated materials, such as chlorinated benzene, chlorinated naphthalene and chlorinated diphenyl, has been introduced wherever their physical properties have made them adaptable. These chlorinated dielectrics have the advantage of having higher dielectric constants and of being made non-inflammable, properties which mineral oil does not possess. The purpose of this,binvestigation is to prepare other chlorinated materials which will possess good dielectric properties and the proper physical characteristics required for use in capacitors and transformers.
