The pyrolysis of a petroleum asphaltene in tetralin donor solvent at 450 °C has been examined, and the products characterized by elemental, molecular weight, n.m.r. and g.c.-m.s. analysis. Degradation to mainly lower molecular weight products takes place, the residual asphaltene having a smaller average cluster size, higher aromaticity and a heteroatom content resistant to further reaction. ß-bond scission is important in the early stages of reaction. © 1985.
