Abstract  

The radiolysis of the CHCl3-water two-phase system in the absence of oxygen has been investigated by continuous -ray irradiation. The major products of radiolysis were determined to be the same, except for tetrachloromethane, as in the case of the radiolysis of pure CHCl3, however, the radiolytical yields were different. The dependencies of gross radiation yields of the radiolysis products on the CHCl3 volume fraction follow the two-phase rule of additivity. The partial yields of all products determined were calculated for both phases and revealed that the major products HCl and C2H2Cl4 are formed in both phases. The other organic products are formed mainly in the organic phase. The decrease of organic product yields is probably caused by the presence of water in the organic phase. The radiolysis of CHCl3-water did not proceed in the diffusional regime even at high absorbed doses due to the relatively high solubility of CHCl3 in water andvice versa.

Abstract  

The radiation-induced oxidation of bis/1,2-dicarbollyl/cobalt/III/ acid by OH radicals in deaerated/aerated aqueous solutions has been investigated. 8-Monohydroxy-, and 8,8-dihydroxy-derivatives have been identified as products of the -radiolysis. For the different conditions the following radiationchemical yields were observed: in the presence of N2 atmosphere G/OHDCC/=1.58, in aerated solution 2.11 and 3.04 in a solution saturated with CCl3.
