42.褐炭の化学構造解析

抄録

To develop the advanced application of brown coal, structural study on Australian Yallourn and Indonesian South Banko coals was carried out by using Curie-point pyrolysis and solid state NMR spectroscopy. Since brown coal contains much oxygen (>20wt%), analyses of the oxygen functionalities were thought to be important. As for molecular weight of the brown coals, GPC analyses of extracts were carried out. On the basis of the above data, chemical structural features and properties of the brown coals were discussed.
