ANALYTICAL STUDY OF BIOMASS PYROLYSIS OILS .2. OPTIMIZATION OF ANALYTICAL CONDITIONS FOR THE PHENOLIC FRACTION USING MICELLAR ELECTROKINETIC CHROMATOGRAPHY

Biomass carbonization oils constitute an important source of chemicals and more recently an alternative energy source to fossil oils, and nu merous studies have been carried out in order to establish their compo sition. As phenol derivatives (alkyl- and methoxyphenols, alkyldihydro xybenzenes, hydroxybenzaldehydes) and naphthol derivatives are product s of high value, they are important components of these complex organi c matrices. A study is reported of the electrophoretic behaviour of th ese compounds using micellar electrokinetic chromatography and, using a mixture of 22 model phenolic derivatives, the possibility of analysi ng such a complex matrix with such a broad lipophilic range in one run is demonstrated.
