Summary
Research on coal structural analysis continues. Significant progress has been made in developing a new NMR approach to the reaction in which the phosphorus-containing product incorporates two ³¹P nuclei for every water molecule reacted. The latter circumstance allows more precise values of low water contents to be realized owing to better integration of the ³¹P NMR peak. We have measured a series of model pyridine/H₂O mixtures by our technique and the results are summarized here. Also collected are similar analyses with pyridine extracts of Argonne Premium coal samples. Results seem to indicate that tightly bound water is being released by pyridine. Further experiments are planned to elucidate this possibility.
