The molecular constitutions of the coexisting anisotropic and isotropic phases of a heattreated petroleum pitch were studied as a function of heat treatment time. The results show that the coexisting phases. which were isolated by high temperature centrifuging, contain different proportions of simil

The sensitivity of side chains on the isotropic content in a mesophase containing pitch was quantified after subjecting the decant oil based mesophase pitch to a series of Friedel-Crafts alkylation reactions. These data were then used to quantify the relative influence of concurrent thermal dealkyla
Heat-treatment processes of various pitches have been monitored by the UV-visible and near-IR spectra measured with the diffuse reflectance method. The shape and intensity of the observed absorption bands changed with the heat treatment of the pitches, reflecting the size of the aromatic molecules a
