derived from the parent cmpd
Biphenyl by chlorination (EAS).
• PCBs were used as dielectric coolant fluids in transformers & capacitors.
• Excellent
electrical & thermal insulation,
low flammability & slight vapour pressure, chemically inert. High KOW low H2O solubility

• The chlorination
proceeds at each of the
positions resulting in mixtures of the 209
congeners (member of a family of related cmpds,
the family is based on structure/functional grps).
