PAH were detected in different phases (gas phase, adsorbed on soot, and stuck on the reactor walls) and quantified by gas chromatography-mass spectrometry (GC\u2013MS). Additionally, the toxicity of the PAH samples, expressed as B[a]P-eq, was analyzed in all experiments.

The main results showed that, at low temperatures, the highest concentrations of PAH were found in the gas phase, while at high temperatures were found on soot. For both inlet concentrations of DMM, the light PAH, such as naphthalene and acenaphthylene, were found in major concentrations, in all phases and temperatures. The heavy PAH, such as fluoranthene and pyrene, increased its concentration on soot at highest temperatures. The highest formation of soot was obtained at 1475\u00a0K and follows the trend: 2,5DMF\u00a0<\u00a0tert-butanol\u00a0<\u00a02MF\u00a0<\u00a02butanol\u00a0<\u00a0iso-butanol\u00a0<\u00a01-butanol\u00a0<\u00a0ethanol\u00a0<\u00a0DMC\u00a0<\u00a0DMM.
