This paper aims at determining the induction period and the rate of formation of the mesophase in thermolysis of pitches from residues differing in origin. In the thermolysis of isotropic petroleum residues that are mainly of secondary origin, an anistropic phase is formed, the so-called mesophase, similar in strucure to liquid crystals. IR spectroscopic data indicate a considerable content of aromatic hydrocarbons in the pitches. These results also indicate the predominance of aromatic hydrocarbons in the pitches. The formation of an anisotropic phase in the thermolysis of petroleum pitches is explained by the presence of ''blanks'' in these pitches--planar polyaromatic hydrocarbon fragments with a paraffinic-napthenic framework.
