| Abstract: | Long-chain aliphatic materials present in coals are not completely oxidized using the procedure described by Deno (Fuel 1978, 57, 455). They are adsorbed on the filter cake during the work-up procedure and can be isolated by extracting the filter cake. The amounts present are similar to those observed by Hayatsu et al. (Fuel in press). Also-phenol is not completely oxidized under these conditions, but gives products with m/e as high as 310. Products from the oxidation of phenol include ethane and propane tricarboxylic acids and benzene tri- and tetracarboxylic acids. |
