✦ Synopsis
The oxidation of Illinois No. 6 coal proceeds readily with ruthenium(VII1)
to provide a mixture of aliphatic and aromatic carboxylic acids. The acids were converted into their methyl esters for analysis by g.c.-m.s. and g.c.-FT-i.r.
spectroscopy.
Mono-, di-, tri-and tetracarboxylic acids are the principal products of the oxidation of this bituminous coal. The g.c.-FT-i.r.
approach has enabled the detection of several different lactones that have not been observed previously. The results imply that cyclic ethers are present in low abundance in Illinois coals.
