“…At high doses the CgHs^^Cl yield in pure CsHsCl increases by about 20%, but this increase is easily scavenged with I2 or unsaturated organic Compounds (Table 1), which means that thermal atoms or radicals are involved. A reaction between atoms and radiolytically produced -CsHs radicals seems obvious, because the G-value for the decomposition of CgHsCl into 'CgHs + -Cl is about 5 -6, as measured in pure and scavenged systems [23,24,25], However, the increase in the CeH; yield goes at the expense of the inorganic yield and, as we will discuss further in the paragraph on the inorganic yield, we believe that this increase is caused by thermal for-Cl exchange with C1 atoms that are generated by a radiation induced conversion of inorganic products. The addition of scavengers prevents the thermal exchange reaction completely, which suggests that the thermal ^'Cl atoms can diffuse freely over many molecular distances before ipso addition takes place.…”

The reactions of recoil " C1 atoms (produced in a high flux nuclear reactor) with liquid chlorobenzenes were investigated. The yields of " CI-for-H and Q-replacement reactions, of inorganic Compounds and of polymers were measured in the presence of scavengers, by GLCtechniques and by gelfiltration over Sephadex. In unscavenged chlorobenzene, C^ Hj" C1 (52%) is formed via a direct hot replacement reaction (5%), via a thermal exchange reaction (28%) and via a radiation induced exchange reaction (19%). It is believed that hot H-abstraction leads to the inorganic yield, because this yield is not influenced by the addition of organic unsaturated Compounds. The total organic yield is not in-fluenced by the addition of organic scavengers, but the natura of the products depends considerably on the kind of scavenger used.Ophthalmie Research Institute (lOI)

“…It has been demonstrated that halogenoaromatic compounds in benzene and its analogous solvents were converted easily to phenylated products by UV irradiation. 2,[6][7][8][9][10][11]14,15) These works reveal that the photolysis of the halogenoaromatic compounds in the aromatic solvents may occur via phenyl radicals.…”

Photolysis of Chlorothalonil in Benzene

Chlorothalonil (tetrachloroisophtalonitrile) in benzene was unstable at a light place and unknown compounds appeared. This reaction occurred easily by sunlight through glass. A major photolysate of chlorothalonil in benzene was crystallized as colorless needles. The photolysate was identified as 2, 3, 5-trichloro-4, 6-dicyanobiphenyl by means of MS and CMR spectra. Similar photolysates of chlorothalonil occurred easily in other aromatic solvents at the light place and gave 3 peaks in toluene, 1 in o-xylene and 2 in mesitylene on the gas chromatogram, but no photochemical products was found in acetone, ether and hexane.

“…The primary dissociation reaction may take place directly through dissociation of excited molecules or indirectly through ionic intermediates 12 . Radiolysis of chlorotoluenes possibly lead to ionization, excitation and electrons react by dissociative electron attachment 13 .…”

Gamma radiation induced formation of ICl in aerated and deaerated solutions of iodine in some aromatic chlorinated solvents has been studied for different concentrations and γ dosages. G values for formation of ICl and decomposition of I 2 were determined in gamma radiolysis of aerated and deaerated solutions of I 2 in 1,2-dichlorobenzene(1,2-DCB), 1,3-dichlorobenzene(1,3-DCB), 2-chlorotoluene, 3-chlorotoluene and benzotrichloride. G(ICl) values have been found to decrease in the following order 2-chlorotoluene < 3-chlorotoluene < 1,2-DCB < 1,3-DCB < benzotrichloride. G(ICl) is slightly higher in aerated solutions than in deaerated solutions and is found to be dependent on the structure of the parent organic molecule.
