Abstract
Improvements introduced in electrical capacitors characterized in that they comprise at least two electrodes and a dielectric sheet placed between them, the dielectric sheet and the gaps between the dielectric sheet and the electrodes impregnated with a liquid dielectric composition comprising at least one ketone having an atmospheric boiling point greater than about 150ºC and represented by the structure. **(See formula)** wherein R1 and R2 have a combined carbon atom content of less than 20 and are individually alkyl, alkenyl, phenyl, tolyl, naphthyl, substituted phenyl, substituted tolyl, or substituted naphthyl, wherein the substituted aromatic radicals individually contain no more than 18 carbon atoms; R1 and R2 may further be part of the same portion comprising a cyclic ketone wherein R1 and R2 together provide 4 or more contiguous carbon atoms to form a chain; R3 and R4 are individually hydrogen or C1 to C8 alkyl; n is zero or 1; and m is an integer from zero to 6 provided that if n and m are 1 then neither R3 nor R4 can be hydrogen.
