Abstract

An insulating cooling liquid for electrical equipment. .F4-. Chlorinated aromatic hydrocarbons (I) are stabilised with 0.001-10% (esp. 0.05-1%) by wt. of 4,4'-bis(2,3-epoxypropoxy)-diphenyldimethylmethane and with 0.001-0.1% of a amine, which may be aliphatic, cycloaliphatic, arylaliphatic or a mixture. Preferably (I) are chlorinated diphenyl with 40-60% Cl, or mixtures of these with chlorobenzenes with 50-60% Cl. As amine at least one of the following should be present: dibenzylmethylamine, trimethylenetetramine, dicyclohexylamine, or preferably tribenzylamine.
