Abstract: Products of reductive methylation and deuteromethylation of two Polish coals of different rank performed in the potassium/liquid ammonia system were subjected to extraction by dichloromethane. Spectral analysis of the extracts was made. A comparison of H-1 and H-2 NMR spectra indicated that the cleavage of C-C bonds in methylene bridges is of substantial importance for the fragmentation of the coal structure taking place under the effect of potassium in liquid ammonia. This finding was confirmed by results of IR analysis. (C) 1999 Elsevier Science Ltd. All rights reserved.
