Abstract (en)
[origin: US4111824A] A liquid dielectric composition obtained as a result of a process which comproses reacting benzene with ethylene in the presence of an alkylation catalyst to obtain an alkylation product containing largely unreacted benzene, ethylbenzene, polyethylbenezenes and heavier products, separating benzene, ethylbenezene and polyethylbenezenes from said alkylation product and thereafter recovering from said heavier products the entire fraction whose boiling point is in the temperature range of about 255 DEG to about 420 DEG C., preferably about 260 DEG to about 400 DEG C., most preferably about 268 DEG to about 400 DEG C., as said liquid dielectric composition.
