In this study, the authors show that the mass spectrometric composition of coal tars can be predicted from the pyrolysis mass spectra of their parent coals. Curie-point low voltage electron ionization mass spectrometry (CuPy-EIMS) was performed on nineteen coals and on their respective pyrolysis liquids prepared by means of a fixed bed reactor method described elsewhere. Using factor and discriminant analysis techniques, the spectra can be classified and underlying structural variables responsible for the above classification identified. Furthermore, compositional similarities and dissimilarities between the solid samples and their liquids can be brought out using canonical correlation methods. Table I lists the samples, their PSOC numbers, geological origin and the rank information. Of the nineteen coal samples, two are of subbituminous rank, three of high volatile B and C bituminous rank and the remainder of high volatile A bituminous rank. Twelve coals are from the Eastern/Appalachian coal province, six are from the Interior province and one is a Western coal from the Northern Great Plains province.
