01), formic acetic anhydride (0.02 ± 0.01) and peroxyacetyl nitrate (PAN); from n-propyl acetate, acetoxyacetaldehyde (0.22 ± 0.06), formic acetic anhydride (0.28 ± 0.03), acetic acid (0.15 ± 0.02), acetaldehyde (0.35 ± 0.10), peroxypropionyl nitrate (PPN) and probably acetoxypropionaldehyde (0.30 ± 0.10). From these data, oxidation schemes of these two acetates were elucidated. This study reveals
在室温 (298 ± 5 K) 和大气压下,通过以 FTIR 光谱法作为分析装置光解 CH3ONO/醋酸盐/NO 混合物,研究了 OH 诱导的醋酸乙酯和醋酸正丙酯的氧化机制。主要氧化产物及其收率如下:由乙酸乙酯、乙酸(0.75±0.13)、乙酰氧基乙醛(0.15±0.05)、乙酐(0.02±0.01)、甲酸乙酐(0.02±0.01)和过氧乙酰硝酸(平底锅); 来自乙酸正丙酯、乙酰氧基乙醛 (0.22 ± 0.06)、甲酸乙酸酐 (0.28 ± 0.03)、乙酸 (0.15 ± 0.02)、乙醛 (0.35 ± 0.10)、过氧丙酰硝酸酯 (PPN),可能还有乙酰氧基丙醛 (0.30 ± 0.10) . 从这些数据中,阐明了这两种乙酸盐的氧化方案。本研究通过证实 Tuazon 等人最近提出的新型 α-酯重排,特别揭示了乙酸盐的特定反应性。(J.
