AbstractThe interaction between pyridine-“N and both fresh and oxidized coal was studied by means of CP/MAS 15Nn.m.r. In fresh bituminous coal, pyridine interacts only weakly through physical adsorption and hydrogen-bonded complex formation. On the other hand, in oxidized bituminous coal and fresh subbituminous coal the presence of both pyridinium ions and physically sorbed pyridine was observed. The occurrence of proton transfer to pyridine suggests that strongly acidic functions are generated during coal oxidation.
