| Abstract | The examination of the structural characteristics of the substances extracted from four coal samples, using N-methyl-2-pyrrolidinone, was carried out by pyrolysis-field ionization mass spectrometry (Py-FIMS). The extracts are complex mixtures of relatively easily distillable components and of larger entities, supposed to be "oligomeric" parts of the coal structure, which are pyrolyzed above 400-degrees-C with the production of hydroxylated derivatives. Polycondensed structures predominate (4 to 7-8 nuclei) in a wide range of m/z values, mainly 250-350. This work can serve as a basis for further studies on the carbonization process of coals and the role of "the extractible phase" in the first stages of the plastic state and the process of coal softening. |
