Abstract
Four coal tar pitches with distinctive quinoline insoluble (QI) contents, ranging from 13 to 21 wt%, and their toluene soluble (TS), beta-resin and QI solvent fractions have been analyzed. The overall structure of the whole pitches was determined by solid state C-13 NMR, using the quantitative single pulse excitation method, and correlated well with the different weight losses exhibited by the individual pitches using TGA. However, their solvent fractions were found to have very uniform structural characteristics and weight loss profiles, indicating a potential for design of superior binder pitch from other coal sources.
