利用二烷吸收NO2形成的加合物二烷-NO2作为氧化剂，研究了肟在非水体系中温和条件下的氧化裂解.结果表明，二烷-NO2可将肟高产率地转化为相应的醛酮.为肟的选择性氧化裂解及NOx废气治理与利用提供了一条新途径.
The liquid dioxane-NO2 additive was prepared by absorption of NO2 gas into dioxane. Theexperimental results showed that the additive could convert oximes (13 oxime derivatives were test-ed.) to corresponding ketones at room temperature for 2～4. 5 hours, while the NO2 as an original ox-idant was reduced to N2. At molar ratio of oxime to dioxane-NO2 = 4 : 1 the maximum yields of hydra-zone derivatives as a result of reaction with 2,4-dinitrophenylhydrazine could be obtained. The processprovides a pollution-free method for treatment of waste NO2 gas and selective degradation of oximes.
