Abstract
In the preparation of g -hexachlorocyclohexane by chlorination of benzene with irradiation by actinic light the reaction is performed in green light of wavelength 5800 -4900 suitably by means of green fluorescent lamps. In an example benzene is chlorinated in green light from a fluorescent lamp to give hexachlorocyclohexane containing 30-50 per cent of the g -isomer.
