34.室温で溶解した酸化炭の構造解析

抄録

We have succeeded in to dissolve a brown coal oxidized by H_2O_2 up to 92% in polar solvents such as DMF and DMSO. It was found that the oxidation at 60℃ for 2h by H_2O_2 was suitable to introduce many carboxyl groups into coal without destroying the coal structure significantly. The solution was served to several spectroscopic analyses, and average unit structure of the brown coal was presumed to consist of 1.4 aromatic rings attached with 1.0 carboxyl group, 0.6 ketone, 1.9 phenolic OH groups and 0.6 ether group.
