Abstract

1465126 Dielectric composition MONSANTO CO 4 Nov 1974 [5 Nov 1973] 47534/74 Heading C5F [Also in Division H1] A liquid dielectric composition comprises (i) at least one ketone having a boiling point greater than 150‹ C. and having the structure wherein R 1 and R 2 have a combined carbon atom content of less than 20 and are individually alkyl, alkoxyalkyl, phenoxyalkyl, cycloalkyl, alkenyl, phenyl, thienyl, pyridyl, naphthyl, substituted phenyl or substituted naphthyl where each substituted aromatic radical contains no more than 18 carbon atoms; R 1 and R 2 can further be part of the same moiety in a cyclic ketone wherein R 1 and R 2 together provide 4 or more contiguous carbon atoms; R 3 and R 4 are each H or C 1 -C 8 alkyl; n is 0 or 1 and m is 0 or 1-6 provided that if n and m are both 1 then neither R 3 and R 4 can be H; and (ii) 0À001-8 wt. per cent of an epoxide stabilizer. The composition may also contain (iii) an ester of a carboxylic acid, or alkyl benzene, alkyl naphthalene, alkyl biphenyl, alkyl polyphenyl, an alkaryl ether, a diaryl alkane, diaryl ether or alkyl derivatives thereof. A preferred composition comprises (i) dimethyl benzophenone, (ii) 3,4 epoxycyclohexylmethyl- 3,4 - epoxycyclohexane carboxylate and (iii) isopropylbiphenyl.
