Abstract

1336266 Chlorinated diphenyl mixtures RHONE-PROGIL 3 Feb 1972 [5 Feb 1971] 5142/72 Heading C2C [Also in Division H1] A liquid mixture of diphenyl chlorination products useful for impregnation of electrical insulating materials comprises per 100 parts by weight, 25 to 33 parts of the monochlorination product of diphenyl, 28 to 36 parts of a dichlorodiphenyl fraction having at least 50% by weight of the 2,41-isomer and 37 to 43 parts of a trichlorination product of diphenyl. There may also be incorporated a minor quantity of a silicone oil and a purifier for eliminating degradation products.
