REACTIONS OF HYDRATED ELECTRON AND ALCOHOL RADICALS WITH HALOGENATED AROMATIC-COMPOUNDS - A PULSE-RADIOLYSIS STUDY

The bimolecular rate constants for the reaction of e(aq)- with chlorotoluenes, chloronitrobenzenes and chloronitrotoluenes have been determined from the decay of e(aq)-. With chlorotoluenes, e(aq)- reacts by dissociative electron capture without any transient absorption band in 270-500 nm region. In case of chloronitrobenzenes and chloronitrotoluenes, e(aq)- forms a transient band with lambda(max) in 290-310 nm region without any Cl- formation. Hydroxy alkyl radicals, derived from alcohols, do not seem to react with chlorotoluenes whereas a transient species with lambda(max) = 305-315 nm region are formed on addition of hydroxy alkyl radical to -NO2 group of chloronitrobenzenes.
