“…16 So, future works on the reactivity of catechol with ozone should be extended to include the identification and quantification of degradation products formed both in gas-and particle-phases. This will be helpful for a better understanding of the chemical mechanisms involved in the catechol ozonolysis.…”

The kinetic reactions of 1,2-benzenediol (catechol) and 2-methoxyphenol (guaiacol) with ozone were studied in a simulation chamber (8 m(3)) under dark conditions. The rate coefficients were measured at 294 ± 2 K, atmospheric pressure and dry conditions (relative humidity, RH < 1%), except for 1,2-benzenediol where they were also measured as a function of relative humidity (RH = 1-80%). The concentrations of organic compounds were followed by a PTR-ToF-MS for a continuous monitoring of gas-phase species. The O3 rate coefficients were obtained using both the pseudo-first-order and relative rate methods. The values (in cm(3) molecule(-1) s(-1)) determined for catechol and guaiacol under dry conditions are (13.5 ± 1.1) × 10(-18) and (0.40 ± 0.31) × 10(-18), respectively. The rate coefficient of catechol was found to be independent of RH below 20% and above 60%, whereas for RH between 20% and 60% it decreases with increasing RH. The determined rate coefficients have been used to evaluate the atmospheric lifetime of each compound with respect to O3. To our knowledge, this study represents the first determination of the ozone rate coefficient with guaiacol and is also the first kinetic investigation for the influence of the relative humidity on the oxygenated aromatic ozonolysis.

“…Catechol has been found as intermediate of the oxidation of phenol by AOPs like O 3 [25,26], UV/O 3 [26], high frequency sonochemistry [26], and Fenton, photo-Fenton, and related processes [27,28]. The efficient destruction of catechol by O 3 [29,30], UV/H 2 O 2 [31], TiO 2 /UV photocatalysis [29,32,33], and Fenton and photo-Fenton processes [33] has been described. However, Lofrano et al [33] did not optimize the experimental conditions for the latter two processes.…”

Catechol is one of the most abundant phenolic components of olive mill wastewaters. In this article, the mineralization of this compound in synthetic aqueous solutions by the Fenton and photo-Fenton processes is studied. It has been found that for 1.44 mM catechol, the total organic carbon of solutions is reduced about 94.4% at best after 60 min of Fenton treatment at optimized conditions of pH 3.0, 0.2 mM Fe 2þ , 7.09 mM H 2 O 2 , and 258C. A faster and overall mineralization is attained by applying photo-Fenton with UVA irradiation. o-Benzoquinone, 1,2,3-trihydroxybenzene and 1,2,4-trihydroxybenzene were identified by GC-MS as primary quinonic and polyhydroxylated derivatives. Small amounts of generated carboxylic acids like muconic, maleic, malonic, acetic, oxalic, and formic acids were detected by ion-exclusion chromatography. The Fe(III) complexes of these acids persist in the medium under Fenton conditions, while their photolysis by UVA light and that of other by-products account for by the faster degradation and total mineralization achieved in the photo-Fenton process. A reaction sequence for catechol mineralization by Fenton and photo-Fenton involving all intermediates detected is proposed.Abbreviations: AOPs, advanced oxidation processes; TOC, total organic carbon 878

“…Such phenolic compounds are used in ozonolysis and photooxidation studies to simulate the chemical fate and aerosol forming potential of such biomass burning intermediates in the atmosphere. Often these include candidate compounds such as phenol and catechol (Atkinson et al, 1992;Olariu, 2001;Olariu et al, 2002;Berndt and Boge, 2003;Tomas et al, 2003;Coeur-Tourneur et al, 2009;Iinuma et al, 2010;Nakao et al, 2011;Ofner et al, 2011). Many of these com-pounds can also serve as model systems for understanding aerosol formation from humic substances, the role of water, and associated heterogenous processes (Ammann et al, 2005;Nieto-Gligorovski et al, 2008;Ofner et al, 2010Ofner et al, , 2011Sun et al, 2010).…”

The formation of secondary organic aerosol from oxidation of phenol, guaiacol (2-methoxyphenol), and syringol (2,6-dimethoxyphenol), major components of biomass burning, is described. Photooxidation experiments were conducted in the Caltech laboratory chambers under low-NOx (<10 ppb) conditions using H2O2 as the OH source. Secondary organic aerosol (SOA) yields (ratio of mass of SOA formed to mass of primary organic reacted) greater than 25% are observed. Aerosol growth is rapid and linear with the primary organic conversion, consistent with the formation of essentially non-volatile products. Gas- and aerosol-phase oxidation products from the guaiacol system provide insight into the chemical mechanisms responsible for SOA formation. Syringol SOA yields are lower than those of phenol and guaiacol, likely due to novel methoxy group chemistry that leads to early fragmentation in the gas-phase photooxidation. Atomic oxygen to carbon (O:C) ratios calculated from high-resolution-time-of-flight Aerodyne Aerosol Mass Spectrometer (HR-ToF-AMS) measurements of the SOA in all three systems are ~0.9, which represent among the highest such ratios achieved in laboratory chamber experiments and are similar to that of aged atmospheric organic aerosol. The global contribution of SOA from intermediate volatility and semivolatile organic compounds has been shown to be substantial (Pye and Seinfeld, 2010). An approach to representing SOA formation from biomass burning emissions in atmospheric models could involve one or more surrogate species for which aerosol formation under well-controlled conditions has been quantified. The present work provides data for such an approach
