Characterization of condensates from peat and bark drying

An analytical system for determining the composition of condensates from the steam drying of peat and bark was developed. Both hydrophilic and lipophilic compounds could be separated by gas-liquid and liquid chromatographic methods. The dominant compound groups in the peat and pine bark condensates were carboxylic acids, aldehydes and monosaccharides, whereas the main compound groups detected in the birch bark condensate included carboxylic acids and terpenoids.
