The liquid dioxane-NO2 additive was prepared by absorption of NO2 gas into dioxane. The experimental results showed that the additive could convert oximes (13 oxime derivatives were tested.) to corresponding ketones at room temperature for 2~4.5 hours, while the NO2 as an original oxidant was reduced to N2. At molar ratio of oxime to dioxane-NO2=4:1 the maximum yields of hydrazone derivatives as a result of reaction with 2,4-dinitrophenylhydrazine could be obtained. The process provides a pollution-free method for treatment of waste NO2 gas and selective degradation of oximes.
