The oxidative degradation of fragrant aldehydes by molecular oxygen has been investigated. The oxygen consumption was monitored and the bond dissociation energy (BDE) of the aldehyde C(O)–H bond were calculated by DFT method. The oxidation products were identified by GC/MS. The different pathways accounting for the oxidative degradation are discussed. The main product is the acid, beside the formate
已经研究了分子氧对芳香醛的氧化降解作用。监测耗氧量,并通过DFT方法计算醛C(O)–H键的键离解能(BDE)。氧化产物通过GC / MS鉴定。讨论了造成氧化降解的不同途径。除甲酸酯外,主要产物是酸。两种氧化产物都是由涉及过酸R(CO)OOH的Baeyer-Villiger反应产生的,而次要产物是由酰基过氧自由基R(CO)OO或过酸RC(O )的脱羧得到的氢过氧化物ROOH中间体产生的哦。
