Subse, at 12.243, 16.564, and 23.337 min, the three substances—cumene, AMS, and AP—appear sequentially. Cumene is presumed to be a product of thermal volatilization. In addition, the spectrum obtained for the addition of zinc ions at 24.914 min is that of phenylethyl methyl ether. Furthermore, at 30.670 min, ethanedione, (4-methylphenyl) phenyl, appears. The spectrum of copper ions, α-cumyl alcohol (CA), appears at 24.914 min, and ethanedione, (4-methylphenyl) phenyl, evolves at 30.669 min. The spectrum of ferrous ions shows that the fourth crest is that of α-ethyl-α-methylbenzyl alcohol at 24.914 min. Finally, at 30.669 min, it displays the waveform of dicumyl peroxide (DCP).
