Approximately similar results were observed when n-hexane was replaced with benzene (Table 8.1) graphite electrodes produced a higher concentration of polyynes with a wider distribution of detectable chains in comparison to titanium electrodes. A striking peculiarity of benzene is the formation of a plethora of HPLC DAD detectable PAHs as reported in Table 8.1 (plus others separated by HPLC but not identified on the basis of the electronic absorption spectra), the distribution of the PAHs was richer and...
