Analysis of Phenolic Components in Wood-Pyroligneous Liquid by Gas Chromatography

Constituents in phenol fractions extracted from wood-pyroligneous liquids and its distillates (smoked flavor) were made clear by gas chromatography. Thirteen components were identified by the comparison of retention data with those of known phenols, using various polar columns packed with DC550, DOS, TCP or DEGS+H3PO4 as the stationary phases. Phenol, guaiacol, m-cresol and 2, 6-dimetoxyphenol were found as major components, and as minor components, o-cresol, p-cresol, creosol and xylenols were identified.
