【Abstract】 The liquid dioxane NO 2 additive was prepared by absorption of NO 2 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 NO 2 as an original oxidant was reduced to N 2. At molar ratio of oxime to dioxane NO 2=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 NO 2 gas and selective degradation of oximes.更多还原
