Abstract

New dielectric liq. contains (a) 30-80 wt.% of tri- and/or tetra-chlorobenzenes and (b) 20-70 wt.% of a mono- or poly-(1-5 alkyl)-bi phenyl or terphenyl. The chlorobenzenes are pref. provided by entectic mixt. of 1,2,3-trichloro- and 1,2,4-trichloro-benzenes opt. also contg. 1,2,3,4-tetrachlorobenzenes. The alkylbiphenyl or terphenyl is pref. of formula (I) or (II). In the formula, R1-3 are each 1-5C alkyl and n1-3 are each 0-3 provided that (n1 + n2) = 1-5 and (n1 + n2 + n3) = 1-4. Used in transformers and electrical capacitors, the liquids are non-flammable, to not crystallise or set under normal conditions e.g. at below -10 degrees C have a high clear point, low viscosity, are degradable and non-pollutant and have excellent dielectric properties.
