Abstract

Det beskrives en dlelektrisk væske bestående av en blanding av (metylbenzyl )xylen- og di(metylbenzyl )- xylen-ollgomerer. En fremgangsmåte for syntese av (metylbenzyl)xylen- oligomerer hærman gjennomfører kondensasjonen av metylbenzyl- . klorid CH3-Cf,H4-CH2Cl på xylen eller på lavere oligoraerer av (metylbenzyl)xylen i nærvær av en FRIEDEL-KRAFTS-katalysator.A dielectric liquid is disclosed consisting of a mixture of (methylbenzyl) xylene and di (methylbenzyl) xylene oligomers. A process for the synthesis of (methylbenzyl) xylene oligomers is carried out by the condensation of methylbenzyl. chloride CH3-Cf, H4-CH2Cl on xylene or on lower oligos of (methylbenzyl) xylene in the presence of a FRIEDEL-KRAFTS catalyst.
