| Abstract: | In order to investigate the roles of oxygen, heat and distillation in air-blowing reaction, the polymerization of a coal tar pitch in oxygen reaction, heat-treated reaction and distillation were studied by observing the molecular structures of the material pitches and product pitches with NMR and ESR measurements. It was found that the oxygen reaction was most effective to raise the softening point of the product pitches. This can be mainly ascribed to the polymerization with biphenyl-type bonding and the suppression of the pyrolysis of material in the reaction. On the other hand, the heattreated reaction without oxygen proceeded to the formation of larger peri-condensed aromatics which gave rise to anisotropy of pitches. The distillated pitch increased methylenic bonding between two aromatics in molecule which gave lower molecular orientation. |
