Abstract:
:A relatively simple, rapid sample preparation method has been developed for analysis of low-molecular mass compounds present in soluble coal products generated by microbial coal solubilizing agents. Acidification of the sample followed by direct extraction into hexanes is coupled with gas chromatography/mass spectrometry analysis for characterization of the soluble coal products. Characterization of the products can contribute to a more complete understanding of the solubilization processes involved, provide further information as to the structure of coal and identify products of potential commercial value.
