Pyrene. Phenol. Guaiacol. Syringol It is chemicals called phenols (isomeric cresols, guaiacol and xylenols) in the peat smoke which flavour the malted barley, and so too the whisky.

Molecular Formula C 7 H 8 O 2; Average mass 124.137 Da; Monoisotopic mass 124.052429 Da; ChemSpider ID 447; More details: Systematic name. 2-Methoxyphenol Guaiacol production did not occur in the absence of either a precursor or A. acidoterrestris FB2 and guaiacol was not produced by A. acidoterrestris FB2 in the samples supplemented with ferulic acid. The presence of Alicyclobacillus spp. that has the ability to produce guaiacol, as well as the substrates vanillin or vanillic acid is prerequisite for production of guaiacol.

Jun 12, 2019 Kinetics of guaiacol hydrodeoxygenation (HDO) was studied using supported MoxC–SBA-15 and as a comparison 5 wt% Pt/C under 30 bar

Guaiacol formed in the decarboxylation reaction is oxidized by peroxidase to tetraguaiacol, a chromophoric substance, which is measurable at 470 nm. Soluble, This study investigates the hydrodeoxygenation (HDO) of guaiacol (GUA), a lignin model compound, using two types of catalysts: mono- and bimetallic Rh-based catalysts and classical sulfided CoMo and NiMo catalysts. The former exhibited greater reactivity than the latter. However, substituting some of the Rh ions with another noble metal (i.e., Pd or Pt) produced no positive effect. This study Guaiacol (I) is esterified with acetic anhydride in the presence of a trace of sulfuric acid to form guaiacol acetate (II). Guaiacol acetate treated with anhydrous aluminum chloride at low temperature rearranges to apocynin. The acyl group takes the position para to the hydroxy group rather than to the methoxy group.
