Abstract
19F nuclear magnetic resonance chemical shifts are reported for the hexafluoroacetone adducts of 21 phenols commonly found in coal-derived mixtures. Signals for the adducts of certain phenols not readily separated by gas chromatography, such as the three cresols, are well resolved. Analysis of coal-derived phenol fractions by this procedure is simple and quantitative as long as 2,6-disubstituted compounds are not present, and the mixtures are not too complex.
