Single, pre-separated density fractions representing pure exinite, vitrinite, and inertinite samples from two high volatile bituminous coals are O-alkylated and examined using density gradient centrifugation. Density shifts of macerals are observed when acidic groups in the macerals are alkylated with methyl or butyl groups. Shifts to lower or higher densities are exhibited by all three maceral groups. For inertinites, multiple density bands appear upon 0-alkylation from a single density band of the original inertinite fraction. This suggests that different chemical domains or different macerals can be isolated from individual maceral groups. 21 refs., 14 figs., 3 tabs.
