Abstract
NEW MATERIAL:3,3,3-Trifluoropropylbiphenyl of formula I.
USE: Synthetic oil having excellent electric characteristics and useful esp. as an electrical oil. It has a high dielectric constant and is used as an electrical oil for capacitor. There is no problem of environmental pollution since the compound is biodegradable.
PROCESS: A compound of formula I is obtained by the reaction of biphenyl of formula II and 3,3,3-trifluoropropene of formula III, in the presence of an acid catalyst, e.g. HF, BF3, HF-BF3 etc., at -20W150°C for 1W30hr.
