Abstract (en)
[origin: WO8000894A1] A synthetic oil useful as an insulating fluid in electrical apparatus is prepared by reacting an aromatic compound with the oligomers of four to 12 carbon alpha-olefins containing predominantly at least about 30 carbon atoms up to about 60 carbon atoms. A synthetic insulating oil for electrical power transformers is prepared by reacting benzene in a 1: 1 molar ratio with a tetramer-pentamer mixture obtained by the oligomerization of 1-decene.
