Abstract (en)
[origin: EP0365380A1] The invention relates to a composition comprising at least one electrically insulating oil (A) and at least one product (B) containing at least six carbon atoms and carrying an aldehyde functional group. The Applicant has thus greatly increased the dielectric properties of benzyltoluene and its oligomers (A) by incorporating 3-ethoxy-4-hydroxybenzaldehyde therein. Application of this composition as a dielectric liquid in electrical transformers or capacitors and as a solvent for carbonless copying paper.
