概要
- 論文の詳細を見る
Oxidation products could be separated to several characteristic groups combining fractional precipitation by alkaline earths metals and solvent extractions, and the H/C of the groups was decreased by mild oxidation with KMnO<SUB>4</SUB>.However, there are no good results in yields for obtaining chemicals, and more decomposition of the residue or the large molecular substances which are water soluble will be necessary.Besides, a small amount of 4-nitro, 3-oxy, 1-benzoic acid was derived from the nitrationof the distilled fraction.
