Guest molecules in coal. First quarterly report, September 1-November 31, 1984
The THF extract obtained from the reaction of an Illinois 6 coal with the K-CE reagent (potassium-crown ether) at room temperature and normal pressure was analyzed by /sup 1/H, /sup 13/C NMR and tandem mass spectrometry. The analysis revealed the presence of a homologous series of polymethylene compounds of tetralins, phenols and dihydronaphthalenes. The dihydronaphthalene was a Birch reduction product of naphthalene and arises from the K-CE reduction step. These structures represent the hydrogen rich Guest Molecules of the coal. The significance of these findings is that it indicates tetralin, phenol and naphthalene residues are real and an integral part of the polymethylene component of the coal. In other coal studies tetralin or some aromatic component has always been used and this has always complicated the analysis. 3 figures.
