- P7 Sonolysis of BrCCl_3 : Frequency effect on reaction sites of radical species(Poster Session)
抄録
In order to elucidate frequency effect on sonochemical reactions, sonolysis of BrCCl_3 was examined at different frequencies. Cl_3CCCl_3 was formed in larger amounts at lower frequency than at higher frequency. In the presence of a radical scavenger TEMPO, the yield of the Cl_3CCCl_3 did not decrease at any frequencies. The result indicates that the CCl_3 radical is not released from the cavity, that is the site of the Cl_3CCCl_3 formation is inside the cavity. Frequency profile of H_2O_2 formation was different from that of Cl_3CCCl_3. H_2O_2 formation was effective at higher frequency. This suggests that sonolysis of BrCCl_3 occurs at lower frequency, while sonolysis of H_2O at higher frequency. Sonolysis of BrCCl_3 with 1-octene was also examined. Br,CCl_3-adduct of 1-octene was more effectively produced at 298kHz than other examined frequencies. The result in the presence of 1-octene and TEMPO indicates that the Br,CCl_3-adduct formation proceeds by a chain mechanism in the bulk medium.
