반응 단계
A mixture of 2-methylbenzaldehyde (10.8 g, 90 mmol), hydroxylammonium chloride (9.4 g, 135 mmol), sodium hydroxide (18.0,0.45 mol), ethanol (80 ml) and water (20 ml) was heated at reflux for 1 h. A solution of citric acid (20 g) in water (700 ml) was added and the mixture was left for crystallisation. The precipitate was collected and recrystallised from water to give 8.6 g of 2-methylbenzaldehyde oxime. M.p. 49.0-49.4° C.
