Description/Abstract To better understand the transformation of aliphatic rich materials and lignin-like polymers during catagenesis, oxidative degradation studies of lignite, subbituminous and bituminous coals were carried out using different oxidants.^For comparison with coal oxidation, Green River kerogen and softwood and hardwood lignins were oxidized.^In order to determine how phenolic structures in lignins and lignin-like polymers have been altered during the evolutionary stages of diagenesis, catagenesis and metagenesis, lignin or lignite coal was heated with clay minerals to produce artificial coalification products.^An oxidative degradation study of these artificial coalification products provided some evidence which helps elucidate the alteration of phenolic structures during catagenesis.^Conclusions from the present and previous studies are: (1) at least this lignite and subbituminous coal contain aliphatic rich materials which might have been derived from lipids.^Such materials are no longer identifiable in higher rank coals except cannel coal, because of extensive degradation during catagenesis.^Indeed, trapped volatile compounds extracted from bituminous coals are predominantly aliphatic hydrocarbons which are considered to be degradation products from the macromolecular materials.^However, lignite and anthracite coals contain much less of these hydrocarbons.^During catagenesis aliphatic carbon chains and alicyclics in kerogen are released successively forming crude oil and gas;(2) During diagenesis and early catagenesis lignin polymers are transformed to lignin-like polymers which are incorporated into the low rank coal macromolecules.^At a later stage of catagenesis, these polymers have lost their lignin-like nature as a result of continued and extensive transformation.
