In an earlier investigation, it was shown that synthetic coal macerals can be prepared from selected biological source materials at relatively mild temperatures (150-200 C) in the presence of montmorillonite clay. The solid /sup 13/C NMR evidence strongly suggested that the gross chemical changes associated with these simulated transformations of lignin parallel those previously identified during the initial stages of natural coal formation. In this communication the synthesis and characterization (solid NMR and IR spectroscopy; MS) of (/sup 13/C) lignins and their use to probe the chemistry of coalification are reported. 11 references, 2 figures.
