Abstract
The rearrangement of ${\beta}$-4-nitroazoxybenzene into 4-hydroxy-4'-nitroazobenzene in strongly acidic solutions has been as certained by UV spectrophotometry. The kinetics of the rearrangement in 20 vol. % ethanol and 80 vol. % of aqueous sulfuric acid-water solutions has been studied, and the rearrangement was found to be acid catalyzed pseudo-frst-order reaction. The mechanism of the rearrangement is also discussed.
强酸性溶液 中에서 ${\beta}$-4-Nitroazoxybenzene이 4-Hydroxy-4'-Nitroazobenzene으로 轉位하는 反應을 UV 分光光度法에 의하여 確認하였다. 20Vol%의 알코올과 80Vol.%의 여러가지 농도의 황산수용액에서의 이 轉位反應 反應速度을 究明하였으며, 그 結果 이 反應이 酸觸媒에 의한 擬1次反應임을 알았으며, 또한 이 轉位反應의 機構도 考察하였다.
