摘要：

Several chemical treatments were applied to a vitrain sample. It is assumed that structural modifications play an important role in subsequent solubilization by a methanol-NaOH mixture. The gradual changes of the main functional groups after chemical pretreatment and solubilization reaction were examined by Fourier transform infrared (FT-i.r.) and diffuse reflectance infrared (DRIFT) spectroscopy. The influence of the structural changes on the behaviour of the samples in solvent extraction (conversion) has been studied by sonication experiments, carried out before and after pretreatment and solubilization reaction.
