Identification of aromatic systems by differential pulse voltammetry in the study of the hydropyrolysis of pyrene and coal asphaltenes

Differential pulse voltammetry at the hanging mercury drop electrode has proved effective in determining the identity of the aromatic structures present in the complex mixtures resulting from the hydropyrolysis of pyrene and coal-derived asphaltenes. Voltammetric results are consistent with g.c.-m.s. analyses for low molecular mass fractions, and the method is also applicable to asphaltenes. © 1985.
