ResumoComponents of the toluene-insoluble, tetrahydrofuran-soluble fraction (THFS) of an electrode-binder coal-tar pitch have been characterized by gel-permeation and silica-gel chromatography, 1H and 13C high-resolution n.m.r., i.r. and u.v. spectroscopy, and electron-impact and field-desorption mass spectrometry. Statistically averaged molecular formulae have been proposed for this fraction of coal-tar pitch. The molecules, with molecular masses predominantly 400–900 but extending up to 1200 amu, are largely peri-condensed polynuclear aromatic hydrocarbons, some with alkyl and heteroatom substituents.
