62.RuO_4を用いる穏和な酸化反応を利用した石炭脂肪族成分の化学構造解析

抄録

Carboxylic acids with more than 6 carbons produced from aliphatic constituents in coals by the oxidation with RuO_4 were analyzed by GC-MS. Amounts of mono- and di-carboxylic acids increase by a decrease in coal rank, which tendencies may reflect those of alkyl groups and methylene bridges contained in coals. Maximum amount of alkanes was observed for coals with around 80wt%C. Amounts of alkanes with odd carbon numbers exceeded to those of even ones.
