[en] High-boiling (HB) radiolysis products are defined as a mixture of compounds whose boiling point exceeds that of a substance with double the molecular weight of the original molecule. We used cp benzene further purified to remove trace impurities and thoroughly dehydrated. The irradiation was provided by a ⁶⁰Co γ emitter with a dose rate of 4 Gy/sec at room temperature. The maximum dose was 20 kGy. The total amount of HB products was determined gravimetrically. The main components of the HB benzene radiolysis products are dimers

[en] This paper investigates the formation of diphenyl and phenylcyclohexadiene in the radiolysis of benzene in the presence of the following acetylacetonates: Cr (AA)₃, Mn (AA)₂.2H₂O, Mn (AA)₃, Fe (AA)₂.2H₂O, Fe (AA)₃, Co (AA)₃. It was found that bisacetylacetonatocobalt (II) lowers the radiation chemical yields of the dimers to a substantial degree. It was suggested that the effect is caused by a reaction of addition of free radicals, arising under the action of radiation, to the central ion of the chelate

[en] The formation of gaseous products of the gamma radiolysis of benzene in the presence of Co(acac)₂ was studied, and the radiation-chemical yields of hydrogen, acetylene methane, and ethylene were determined. Spectrophotometric data showed that, as a result of irradiation, oxidation of the additive occurred, with formation of cobalt(III) complexes. Yields of biphenyl and phenylcyclohexadienes were determined in these benzene solutions, and also in systems containing Co(acac)₂ with 18-crown-6. Possible mechanisms of the processes taking place are discussed. 10 refs., 2 tabs

[en] This paper studies the formation of dimer radiolysis products of toluene in the presence of cobalt, iron, and manganese acetylacetonates. It was shown that Ca(AA)₂ substantially lowers the yield of benzylmethylcyclohexadiene but has no specific influence on the yield of dibenzyl. An explanation is cited for the observed effect of acetylacetonates
