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.
